Heart Palpitations and Arrhythmia: When to See a Cardiologist in Hyderabad

By Dr. Bhishma Chowdary Donepudi, FSCAI (USA), Interventional Cardiologist, Hyderabad · Updated 12 October 2026

Most of us have felt it at some point: a sudden flutter, a hard thump, or a brief sense that the heart has "skipped a beat." These sensations, known as palpitations, are among the most common reasons patients in Hyderabad walk into a cardiology clinic. The reassuring news is that the great majority of palpitations are harmless. The important part is knowing which ones are not, and when they point to an underlying arrhythmia that deserves a closer look.

What Are Palpitations, and What Usually Causes Them?

Palpitations are simply an awareness of your own heartbeat, whether it feels fast, pounding, fluttering, or like a missed beat. According to Mayo Clinic, common and usually benign triggers include stress, anxiety, or panic, hard physical exertion, stimulants such as caffeine, nicotine, or certain decongestants, fever, and hormonal shifts related to the menstrual cycle, pregnancy, or menopause. An overactive or underactive thyroid gland can also make the heart race or skip, which is one reason a cardiologist may check thyroid levels when palpitations recur.

• StimulantsCaffeine, nicotine, some decongestants
• Exertion & feverHard exercise or illness
• Hormonal shiftsCycle, pregnancy, menopause
• Thyroid imbalanceOveractive or underactive thyroid
• Heat & dehydrationCommon in Hyderabad summers

In Hyderabad's climate, there is a practical local trigger worth mentioning: heat and dehydration. During the city's peak summer months, local health advisories have repeatedly urged residents, especially those with existing heart conditions, to stay well hydrated. Heavy sweating can shift the body's fluid and electrolyte balance, and that shift can make the heart more prone to racing or skipping. Staying hydrated and avoiding peak-heat exertion is a simple, practical step during Hyderabad summers.

When Palpitations Signal an Arrhythmia

Sometimes what feels like a passing flutter is actually an arrhythmia, an irregular heart rhythm that beats too fast, too slow, or erratically. The most common serious arrhythmia is atrial fibrillation, or AFib, in which the heart's upper chambers beat chaotically instead of in a coordinated rhythm. The Centers for Disease Control and Prevention (CDC) notes that some people with AFib have no symptoms at all, while others experience an irregular heartbeat, palpitations, lightheadedness, fatigue, shortness of breath, or chest discomfort.

AFib matters beyond the uncomfortable sensation it causes. The CDC reports that, after accounting for other risk factors, AFib is associated with roughly a fivefold increase in the risk of ischemic stroke, and that it contributes to about one in seven strokes. This is exactly why persistent or recurrent palpitations are worth evaluating rather than ignoring: when AFib or another arrhythmia is identified early, it can usually be managed with monitoring, lifestyle changes, medication, or procedures that meaningfully reduce that added risk.

Local Context: AFib and Heat in Hyderabad

AFib also appears less common in Indian community populations than in many Western ones: a screening study in rural Andhra Pradesh (the AP-AF study) found it in only 14 of 4,281 people screened. Still, rising rates of hypertension, diabetes, and obesity in urban centers like Hyderabad are known arrhythmia risk factors, which is why unexplained or persistent palpitations are worth checking rather than assuming they're harmless.

When to Worry: Red Flags Versus Harmless Episodes

A brief flutter that lasts a few seconds and passes on its own, especially after coffee, a stressful meeting, or a hard workout, usually does not need urgent evaluation. Mayo Clinic's general guidance is that you should consult a cardiologist if you have a history of heart disease and your palpitations are becoming more frequent or more severe, since monitoring tests may be needed to identify the cause.

Certain symptoms, however, call for emergency care rather than a routine appointment. Seek immediate medical attention if palpitations occur together with chest pain or pressure, fainting or near-fainting, severe shortness of breath, or severe dizziness. These combinations can point to a more serious underlying rhythm problem or reduced blood flow and should never be "waited out."

How Arrhythmias Are Diagnosed and Managed

Diagnosis usually starts with a detailed history and a resting ECG, which captures the heart's electrical activity at that moment. Because many arrhythmias come and go, a Holter monitor (worn for a day or more) or a longer-term event monitor is often used to catch an episode as it happens, alongside an echocardiogram and blood tests for thyroid or electrolyte problems.

Management depends on the cause and severity. For many patients, addressing triggers such as excess caffeine, poor sleep, dehydration, or thyroid imbalance is enough. When a more significant arrhythmia such as AFib is confirmed, options range from rate- or rhythm-controlling medication and stroke-risk reduction to catheter-based procedures in appropriate cases, chosen based on your individual findings rather than a one-size-fits-all approach.
