The normal time of ventricular contraction depends on the heart rate. The QT segment represents the ventricular contraction on an ECG exam. The corrected QT segment is 0.45 seconds for men and 0.46 seconds for women.
The ventricular systole lasts for about 0.3 seconds, during which time the ventricles of the heart contract to push blood out into the arteries.
The Wright Brothers' first powered flight on December 17, 1903, lasted 12 seconds and covered a distance of 120 feet.

Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest. Premature ventricular contractions are common — they occur in many people. They're also called: Premature ventricular complexes Ventricular premature beats Ventricular extrasystoles If you have occasional premature ventricular contractions, but you're otherwise healthy, there's probably no reason for concern, and no need for treatment. If you have frequent premature ventricular contractions or underlying heart disease, you might need treatment.

On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
There are three types of heart rhythms and they include; Supraventricular arrhythmias,Ventricular arrhythmias,Bradyarrhythmias.
