PSVT; Supraventricular tachycardia; Abnormal heart rhythm - PSVT; Arrhythmia - PSVT; Rapid heart rate - PSVT; Fast heart rate - PSVT

Paroxysmal supraventricular tachycardia (PSVT) is episodes of a rapid heart rate that start in a part of the heart above the ventricles. "Paroxysmal" means from time to time.

Conduction system of the heart

The intrinsic conduction system sets the basic rhythm of the beating heart by generating impulses which stimulate the heart to contract.

Holter heart monitor

During a heart Holter monitor study, the patient wears a monitor that records electrical activity of their heart (similarly to the recording of an electrocardiogram). This usually occurs for 24 hours, while at the same time the patient also records a diary of their activity. Health care providers then analyze the recording, tabulate a report of the heart's activity, and correlate irregular heart activity with the entries of the patient's diary.
