Premature ventricular contraction (PVC) is a type of abnormal heartbeat, or arrhythmia. It happens when the heartbeat begins in the lower, rather than the upper, heart chambers. This creates an ...

Future research should focus on testing PVC removal beyond 96 hours, patient preferences for routine or clinically indicated PVC removal, more rigorous studies and use of ultrasound to assess PVC ...

A premature ventricular contraction occurs when a focus in the ventricle generates an action potential before the next scheduled sinoatrial nodal action potential. Premature, occurring earlier than ...

Premature ventricular complexes (PVCs) are extra heartbeats originating from the heart’s lower chambers, potentially causing palpitations or fluttering sensations. While occasional PVCs are common, ...

In most cases, you can exercise at full capacity if you only sometimes experience PVCs. You may need to reduce the intensity if you often experience PVCs or have an underlying heart condition.

Trigeminy is a heart rhythm irregularity characterized by a premature ventricular contraction occurring every third heartbeat. While many people with trigeminy experience no symptoms, others may feel ...

A single noninvasive radiation therapy treatment safely reduced the burden of ventricular tachycardia, with effects persisting for 2 years in most patients, according to data from the ENCORE-VT trial ...
