Most people have felt it at some point—a flutter in the chest, a skipped beat, or the sensation that your heart is racing unexpectedly. These are known as heart palpitations, and while they’re common, they can also be unsettling. Dr. Ian Weisberg, an experienced cardiac electrophysiologist, helps patients navigate the causes and concerns surrounding palpitations, offering clarity, reassurance, and expert care.

What Are Heart Palpitations?

Heart palpitations are the feeling that your heart is beating irregularly. This might include sensations like pounding, fluttering, or a rapid heartbeat. According to Dr. Weisberg, not all palpitations are dangerous—but they should never be ignored.

“Palpitations can be harmless or a sign of something more serious,” he explains. “Understanding the context, frequency, and associated symptoms is key.”

Common Causes

There are several potential causes of heart palpitations, ranging from everyday triggers to underlying medical conditions. Dr. Weisberg identifies some of the most common:

  • Stress and anxiety – Emotional distress can release adrenaline, speeding up the heart.
  • Caffeine and stimulants – Coffee, energy drinks, or certain medications can provoke palpitations.
  • Exercise – Physical activity naturally raises heart rate but shouldn’t cause irregular rhythms post-exercise.
  • Dehydration or electrolyte imbalances – These can disrupt the heart’s electrical system.
  • Arrhythmias – Palpitations may signal a more serious rhythm disorder like atrial fibrillation or supraventricular tachycardia.

“If palpitations are infrequent and short-lived, they’re usually benign,” Dr. Ian Weisberg says. “But if they’re persistent, accompanied by dizziness, shortness of breath, or chest pain, it’s important to seek medical evaluation.”

Diagnosing the Cause

To determine the root of palpitations, Dr. Weisberg employs a variety of diagnostic tools:

  • Electrocardiograms (ECG)
  • Holter or event monitors
  • Stress testing
  • Electrophysiology studies for complex cases

“Capturing the rhythm while the symptoms occur is critical,” he notes. “That helps us determine whether it’s an isolated event or part of a larger arrhythmia.”

Treatment and Management

If palpitations are related to lifestyle or stress, changes such as reducing caffeine, improving sleep, or managing anxiety can often resolve them. For patients with arrhythmias, Dr. Ian Weisberg may recommend medications, catheter ablation, or monitoring devices, depending on the severity.

“Every treatment is tailored to the individual,” he explains. “Our goal is not just to stop the palpitations, but to treat the underlying cause and improve quality of life.”

When in Doubt, Get Checked

Dr. Weisberg encourages anyone experiencing new or concerning palpitations to speak with a healthcare professional.

“Your heart is trying to tell you something,” he says. “It’s always worth listening—and taking action early.
