Ventricular premature beats in a trigeminal pattern are a commonly seen arrhythmia in everyday life. On an electrocardiogram, this arrhythmia typically presents as two normal heartbeats followed by one premature ventricular contraction. This pattern recurs repeatedly and is referred to as ventricular premature beats in a trigeminal pattern. When this occurs, many patients may feel palpitations or a pounding heart, or experience chest tightness. Generally, if there is no structural heart disease present in the patient, this type of premature beat is not hazardous and does not warrant concern.
