What Does an Irregular Heartbeat Mean?

An irregular heartbeat means your heart’s rhythm has slipped out of its usual pattern. It may race, slow down, flutter or skip a beat, and doctors call this an arrhythmia. Sometimes it’s harmless and linked to things like too much chai, stress or poor sleep. At other times it points to a rhythm disorder such as atrial fibrillation or an underlying heart problem, which is why how often it happens and how you feel matter more than a single skipped beat.

According to Dr. S. A. Merchant, an Interventional Cardiologist and Advanced Heart Failure Specialist in Mumbai, “A skipped beat now and then is very common, and most people don’t need to panic. What I look at is the pattern: how often it happens, how long it lasts, and whether it comes with dizziness, breathlessness or chest discomfort. The tricky part is that the rhythm is often normal by the time the patient reaches the clinic, so capturing it on a heart tracing is what gives us the answer.”

• The electrical signal goes off track. Each heartbeat starts as a tiny electrical impulse, and an arrhythmia means that impulse is too fast, too slow or out of sequence.
• The rate changes. A resting rate above 100 beats a minute is called tachycardia, and one below 60 is called bradycardia, though not every case needs treatment.
• It can feel different for everyone. People describe fluttering, pounding, racing or a “missed beat” in the chest or throat.
• Some episodes are silent. You may feel nothing at all, and the rhythm gets picked up during a routine check-up.

A quick tracing of the heart’s electrical activity is the first step, and our vitals and ECG services are set up to do exactly that.

• Everyday triggers. Caffeine, alcohol, stress, lack of sleep and some medicines can set off short-lived palpitations.
• Other health issues. An overactive thyroid, low or high potassium or other salts in the blood, and sleep apnoea can all disturb the rhythm.
• Heart conditions. High blood pressure, valve disease, a past heart attack or heart failure can make the heart more prone to rhythm problems.
• Rhythm disorders themselves. Conditions such as atrial fibrillation or supraventricular tachycardia start in the heart’s own electrical system.

When a rhythm problem needs more than medicines, options such as pacemakers and other procedures come under our cardiac device therapy and interventional procedures service.

• The type of rhythm caught on testing. A harmless extra beat and atrial fibrillation are handled very differently.
• How your body responds. Dizziness, fainting, chest pain or breathlessness during episodes make evaluation more urgent.
• Any underlying cause. Treating a thyroid problem, BP, valve disease or heart weakness can settle the rhythm in some people.
• Your stroke risk and overall health. Age, other illnesses and the rhythm type decide whether medicines, procedures or just monitoring is best.

Key Takeaways

• An irregular heartbeat means the heart rhythm is too fast, too slow or uneven.
• Occasional skipped beats are common and often harmless.
• Frequent, long-lasting episodes, or ones with dizziness, breathlessness, chest pain or fainting, need a medical check.
• An ECG, and sometimes a Holter monitor, helps catch what a normal clinic visit can miss.
• Finding the cause is as important as treating the rhythm
