WebParoxysmal Supraventricular Tachycardia (PSVT) Heart and Vascular Arrhythmias. Paroxysmal supraventricular tachycardia (PSVT) is a type of abnormal heart rhythm, or arrhythmia. It occurs when a short circuit rhythm develops in the upper chamber of the heart. This results in a regular but rapid heartbeat that starts and stops abruptly. WebFeb 27, 2024 · A PVC, or premature ventricular contraction, occurs when an impulse begins in the ventricles and conducts through them prior to the next sinus impulse. PVCs occur within an otherwise normal sinus rhythm. PVCs are characterized by an irregular heartbeat and an oddly-shaped QRS that is ≥0.12 seconds.

WebOct 16, 2016 · The heart in usually bound to two beats at a time, but when one has trigeminy, there is an occurrence of a third premature beat. It is otherwise known as premature ventricular contractions (PVC), probably due to the fact that the third premature beat is usually ectopic, meaning that it starts from another area that is not the sinus node. WebAug 30, 2024 · Trigeminy is a type of heart arrhythmia. The word trigeminy means “occurring in threes.”. The word arrhythmia means “irregular heartbeat.”. Different types of heart arrhythmias are diagnosed based on their irregular beat patterns.

WebDec 2, 2024 · P wave morphology. The P wave typically has a different morphology and axis to the sinus P waves; PACs arising close to the AV node (“low atrial” ectopics) cause retrograde activation of the atria, producing an inverted P wave with a relatively short PR interval ≥ 120 ms (PR interval < 120 ms is classified as a PJC); The abnormal P wave may … WebSep 8, 2024 · When PVCs occur every other beat, it is referred to as ventricular bigeminy, and when they occur every third beat, it is referred to as ventricular trigeminy.
