Poetry can romanticize a lost person Heart palpitations, but in real life, it can seem worrying when your heart suddenly flutters, stops or starts taking extra beats. These sensations are actually a well-documented physiological phenomenon known as an irregular heartbeat or arrhythmia – and although they can be unsettling, they do not always indicate danger. Understanding why they happen, what is normal and when to seek help can make the difference between panic and reassurance.

Dr. Dmitry Yaranov, a cardiologist and heart-transplant specialist specializing in advanced heart failure and mechanical circulatory support, explores the real reason why your heart sometimes skips a beat and whether it’s cause for concern. In an Instagram video shared on January 2 Cardiologists explain the common causes of irregular heartbeats, how they are medically evaluated, and key warning signs that indicate when you should seek further medical evaluation.
Why does the heart stop beating?
According to Dr. Yaranov, your heart doesn’t always beat, but it actually works. He highlighted that PAC (premature atrial contractions) and PVCs (premature ventricular contractions) are both irregular heartbeats that are often harmless but can feel frightening.
The cardiologist explains, “PACs and PVCs are the initial beats. Extra beats. Normal. Often benign. Often frightening when you feel them.” He emphasizes the following important things to know about irregular heart rhythm that people often overlook:
- Experiencing an irregular heartbeat does not mean you are in danger.
- The frequency of arrhythmia matters more than fear.
- Context is everything – the heart’s structure, symptoms and burden need to be analyzed to find the cause of the arrhythmia and rule out underlying complications.
How to tell the root cause?
Dr. Yaranov says that when a person experiences extra heartbeats, cardiologists rely on appropriate diagnostic tests to understand the context and underlying cause rather than guesswork.
He elaborated, “This usually means an ECG to define the rhythm, a monitor to measure how often this is happening, and an echo to make sure the heart’s structure and function are normal. Laboratories when appropriate. Perform ischemic testing only if it fits the story.
What causes irregular heartbeat?
According to the cardiologist, if the heart’s structure is normal, its function is preserved and no dangerous patterns are visible on testing, the next step is often to identify possible triggers or causes behind the arrhythmia rather than assuming a serious problem. He outlined the following as possible culprits:
- Tension
- caffeine
- poor sleep
- dehydration
When does it become worrying?
Irregular heartbeats caused by the factors mentioned above usually do not indicate any serious condition or immediate cause for concern. However, if they are persistent or are accompanied by other symptoms, it is important to have them evaluated by a medical professional.
He emphasizes, “Evaluate persistent symptoms, high burden, dizziness, fainting, or underlying heart disease. Boring tests save the drama for later. Medicine is not about dismissing symptoms. It is about knowing when to rule out danger, ignore the noise, and when to take action.”
