WebOct 12, 2024 · This results in well organised synchronised ventricular depolarisation. A broad QRS complex occurs if there is an abnormal depolarisation sequence – for example, a ventricular ectopic where the impulse spreads slowly across the myocardium from the focus in the ventricle. In contrast, an atrial ectopic would result in a narrow QRS complex ... WebResults.

WebThree or more successive PVCs are termed ventricular tachycardia (VT). ECG characteristics are: Rate: Depends on the underlying rhythm Ectopic beats: Yes. Rhythm: Regular P wave: Visibility of P wave depends on the timing of the PVC; may be absent (hidden in the QRS or T wave) or in front of the QRS. WebEctopic heartbeats are sometimes seen with: Changes in the blood, such as a low potassium level ( hypokalemia) Decrease in blood supply to the heart. When the heart is enlarged or structurally abnormal. Ectopic beats may be caused or made worse by smoking, alcohol use, caffeine, stimulant medicines, and some street drugs.

WebJan 13, 2024 · Background. A premature ventricular contraction (PVC) is caused by an ectopic cardiac pacemaker located in the ventricle.
