"New research from Karolinska Institutet and Columbia University shows that the heart has a mini-brain – its own nervous system that controls the heartbeat. A better understanding of this system, which is much more diverse and complex than previously thought, could lead to new treatments for heart diseases.

The study, conducted on zebrafish, is published in Nature Communications."

"The heart has long been thought to be controlled solely by the autonomic nervous system, which transmits signals from the brain. The heart’s neural network, which is embedded in the superficial layers of the heart wall, has been considered a simple structure that relays the signals from the brain. However, recent research suggests that it has a more advanced function than that.

Controlling the heartbeat

Scientists have now discovered that the heart has its own complex nervous system that is crucial to controlling its rhythm.

“This ‘little brain’ has a key role in maintaining and controlling the heartbeat, similar to how the brain regulates rhythmic functions such as locomotion and breathing,” explains Konstantinos Ampatzis, principal researcher and docent at the Department of Neuroscience, Karolinska Institutet, Sweden, who led the study.

The researchers identified several types of neurons in the heart that have different functions, including a small group of neurons with pacemaker properties. The finding challenges the current view on how the heartbeat is controlled, which may have clinical implications.

Similar to the human heart

“We were surprised to see how complex the nervous system within the heart is,” says Konstantinos Ampatzis.

“Understanding this system better could lead to new insights into heart diseases and help develop new treatments for diseases such as arrhythmias.”

The study was conducted on zebrafish, an animal model that exhibits strong similarities to human heart rate and overall cardiac function. The researchers were able to map out the composition, organisation and function of neurons within the heart using a combination of methods such as single-cell RNA sequencing, anatomical studies and electrophysiological techniques."

An irregular heartbeat, medically known as an arrhythmia, occurs when the heart beats too quickly, too slowly, or with an abnormal rhythm. Some rhythm changes are harmless, while others may require medical evaluation and ongoing treatment. Understanding the possible causes, warning signs, diagnostic tests, and available irregular heartbeat treatment options can help people seek appropriate care at the right time.

What Is an Irregular Heartbeat?

A healthy heart normally follows a regular electrical rhythm that coordinates each heartbeat. An arrhythmia can develop when electrical signals in the heart are generated or transmitted abnormally. Depending on the type, a person may experience palpitations, a racing heartbeat, skipped beats, dizziness, weakness, or shortness of breath.

Some people may not notice any symptoms at all, and an irregular rhythm may only be detected during a routine examination. This is why appropriate cardiac assessment can be important, particularly for people with existing cardiovascular risk factors.

Common Causes of Irregular Heartbeat

Several factors can contribute to abnormal heart rhythms. These may include:

High blood pressure and other cardiovascular conditions

Coronary artery disease or previous heart-related problems

Electrolyte imbalances involving potassium, magnesium, or calcium

Thyroid disorders

Certain prescription or over-the-counter medicines

Excessive caffeine or alcohol consumption

Smoking and other lifestyle factors

Emotional stress and lack of adequate sleep

Structural abnormalities of the heart

Age-related changes in the cardiovascular system

Some arrhythmias can also occur because of problems affecting the heart's electrical conduction system. Identifying the underlying cause is essential because treatment depends on the specific type of rhythm disturbance.

Symptoms That Should Not Be Ignored

The symptoms of an abnormal heart rhythm can vary considerably. Common signs include:

A sensation of fluttering or pounding in the chest

Fast or unusually slow heartbeat

Feeling that the heart has skipped a beat

Dizziness or light-headedness

Unexplained tiredness

Breathlessness

Chest discomfort

Reduced ability to perform normal physical activities

Fainting or near-fainting episodes

Severe chest pain, significant breathing difficulty, fainting, or sudden weakness requires urgent medical attention rather than waiting for a routine appointment.

How Is an Irregular Heartbeat Diagnosed?

Diagnosis usually begins with a medical history and physical examination. A doctor may ask about symptoms, medications, lifestyle habits, previous medical conditions, and family history.

A heart check up near me may include several investigations depending on the symptoms and suspected rhythm problem. Common diagnostic methods include:

Electrocardiogram (ECG): Records the heart's electrical activity and can identify many rhythm abnormalities.

Holter monitoring: A portable device records heart rhythm continuously, often for 24–48 hours or longer.

Event monitoring: Useful when symptoms occur less frequently and need to be captured over a longer period.

Echocardiogram: Uses ultrasound to assess heart structure and pumping function.

Blood tests: May check thyroid function and electrolyte levels.

Stress testing: Can evaluate how the heart responds to physical activity in selected patients.

These tests help doctors determine whether symptoms are caused by an arrhythmia and identify the specific rhythm involved.

Modern Irregular Heartbeat Treatment Options

Treatment depends on the type of arrhythmia, its cause, symptoms, and the patient's overall cardiovascular health. Some people may only require regular monitoring and lifestyle adjustments, while others may need medicines or specialised procedures.

Medication may be prescribed to control heart rate or restore and maintain a normal rhythm. In selected cases, medicines may also be used to reduce the risk of blood clots associated with certain arrhythmias.

For people who also have hypertension, consultation with a high blood pressure specialist may help address an important cardiovascular risk factor. Controlling blood pressure, maintaining a healthy weight, exercising appropriately, avoiding tobacco, limiting excessive alcohol, and managing stress can support overall heart health.

For certain rhythm disorders, advanced procedures may be considered. These can include electrical cardioversion, catheter-based ablation, pacemaker implantation, or implantable cardioverter-defibrillator placement. The appropriate approach is determined after detailed cardiac evaluation.

When Should You Consult a Cardiologist?

Recurring palpitations, unexplained dizziness, fainting, or persistent changes in heart rate should not be ignored. A cardiologist can assess whether the symptoms represent a harmless rhythm variation or a condition requiring treatment.

People searching for the best cardiologist in Mumbai should consider factors such as relevant clinical experience, access to diagnostic facilities, availability of cardiac monitoring, and the ability to provide coordinated care when specialised treatment is required.

At Sushrut Hospital, cardiac services are supported by a dedicated Cath Lab/Cardiac Care Unit and multidisciplinary hospital facilities, allowing patients to undergo appropriate evaluation and treatment based on their individual needs.

Lifestyle Measures That May Support Heart Health

Lifestyle changes cannot replace medical treatment when an arrhythmia requires clinical management, but they may support cardiovascular health.

Helpful measures can include:

Follow a balanced diet with appropriate portions of fruits, vegetables, whole grains, and protein.

Maintain regular physical activity according to medical advice.

Limit excessive caffeine if it triggers palpitations.

Avoid smoking and tobacco products.

Manage stress through relaxation, adequate sleep, and healthy routines.

Take prescribed medicines exactly as directed.

Monitor blood pressure and other relevant health measurements.

Attend follow-up appointments and recommended cardiac tests.

It is also useful to keep a record of when palpitations occur, how long they last, and whether they are associated with exercise, stress, caffeine, or other triggers. This information can help a doctor during evaluation.

5 Frequently Asked Questions

1. What is the first step in irregular heartbeat treatment?

The first step is identifying the type and cause of the arrhythmia. A clinical examination, ECG, blood tests, or longer-term rhythm monitoring may be recommended before selecting treatment.

2. Can high blood pressure cause an irregular heartbeat?

Yes. Long-term uncontrolled blood pressure can place additional strain on the heart and may increase the risk of certain rhythm problems. Managing blood pressure is therefore an important part of cardiovascular care.

3. When should I seek emergency care for an irregular heartbeat?

Seek urgent medical attention if an abnormal heartbeat occurs with severe chest pain, fainting, significant breathlessness, sudden weakness, or other severe symptoms.

4. Can lifestyle changes stop heart palpitations?

Lifestyle measures may reduce palpitations when triggers such as excessive caffeine, alcohol, smoking, stress, or poor sleep are involved. However, recurring symptoms should still be medically evaluated.

Let's talk about coronary artery bypass surgery, or CABG, if you want to sound like you know what you're doing at a dinner party (please don't, it's a weird flex).

Here's the deal: your heart runs on a network of blood vessels called coronary arteries. Over time, plaque can build up inside them, narrowing the pathways and choking off the oxygen-rich blood your heart muscle needs to keep doing its very important job. This is coronary artery disease, and left unmanaged, it's a fast track to chest pain, breathlessness, and eventually a heart attack.

CABG is basically your body's detour system. Surgeons take a healthy blood vessel from somewhere else in your body — often the leg, chest, or arm — and use it to build a new route around the blocked artery. Traffic (aka blood) gets rerouted, your heart starts breathing easier (metaphorically), and the whole system gets a second chance.

A few things worth knowing if this is on your radar:

🕐 It's not quick. The surgery itself usually takes 3 to 6 hours, depending on how many arteries need bypassing and how complicated your case is.

🏥 You'll be in for a bit. Hospital stays typically run 5 to 7 days, and full recovery stretches out to 6-12 weeks. This isn't a "surgery on Monday, back to spin class Wednesday" situation — your body needs real time to heal.

😴 General anesthesia is standard, so you'll be fully out for the procedure.

📈 The success rates are genuinely reassuring. Modern CABG procedures have a high clinical success rate, and most patients report real, lasting improvement — less chest pain, better stamina, and a noticeably better quality of life once they're through recovery.

💰 Cost varies a lot depending on the hospital, the surgeon, and how complex the surgery is, so it's worth getting a real quote rather than assuming a number.

Why people choose it: when arteries are too blocked for less invasive options like stents, bypass surgery is often the move that actually addresses the root problem instead of just managing symptoms. It's a bigger commitment upfront, but for a lot of people it means genuinely getting their life back — going back to work, playing with their kids, walking up a flight of stairs without their chest screaming at them.

If you or someone you love is facing this, the biggest thing to remember is: ask questions. Ask about the surgeon's experience, ask about recovery logistics, ask about cost breakdowns. A good care team should be walking you through every step, not just the surgery itself but the consultations, tests, and follow-ups on either side of it.

This is actually where platforms like GetBeds come in handy — instead of cold-calling hospitals and hoping for the best, you can look up cardiac specialists, compare surgery packages, and get transparent pricing all in one place, with a care manager walking you through the whole journey from first consult to follow-up.

When coronary arteries become narrowed or blocked, doctors may recommend Angioplasty or Bypass Surgery depending on the patient’s condition. While both treatments aim to improve blood flow to the heart, they differ significantly in their procedure, recovery time, and suitability.

Angioplasty is a minimally invasive procedure that uses a catheter, balloon, and often a stent to open a narrowed or blocked artery. Bypass Surgery (CABG) creates a new route for blood flow around the blocked portion using a healthy blood vessel graft. The choice between the two depends on factors such as the number, location, and severity of blockages, heart function, diabetes, and overall health.

There is no single treatment that is best for every patient. A Cardiologist and Cardiac Surgery team determine the most appropriate approach after evaluating medical reports and the patient’s individual condition.
