What Causes Premature Heartbeats?
Clinically, “premature heartbeats” (or premature ventricular contractions, PVCs) refer to early cardiac contractions that occur before the next expected heartbeat in an otherwise normal cardiac rhythm. These may occur in healthy individuals as well as in patients with underlying heart disease. Common symptoms include palpitations and the sensation of skipped or missed heartbeats. So, what causes premature heartbeats?
Causes of Premature Heartbeats
Premature heartbeats may arise from the following causes: First, untreated or inadequately managed coronary artery disease (CAD) can trigger premature beats. Treatment options include compound Danshen dripping pills or Shenrong Yangxin capsules. Second, premature contractions originating outside the heart (ectopic beats) may result from myocardial ischemia (inadequate blood supply to the heart muscle) or arrhythmias. Medications such as isosorbide nitrate or dipyridamole may be prescribed; combination therapy with aspirin often yields favorable outcomes.

Third, premature cardiac contractions may be triggered by angina pectoris. Sublingual nitroglycerin is commonly used for acute relief. In cases of severe underlying heart disease, radiofrequency ablation or surgical intervention may be required.

Dietary recommendations for patients include low-fat and low-sodium intake. Smoking and alcohol consumption should be avoided entirely. Regular moderate physical activity—such as jogging or brisk walking—is encouraged to improve cardiopulmonary function and enhance immune system resilience. Additionally, maintaining a consistent daily routine—including early bedtime and wake-up times—and avoiding late-night activities helps prevent physical exhaustion.
