consecutive 3 or more than 3 ventricular ectopic beats, QRS wave group the majority of malformations ,[link widoczny dla zalogowanych], QRS time than 0.12 seconds, the basic law of uniform ventricular Qi, frequency and more for the 140-200 beats / min, may have to reverse the secondary ST-T, and occasionally be able to see the inherent link to sinus rhythm P waves blend in the QRS wave difference parts of the event won the meet by the ventricular timing can occur (Figure -2).
first aid emergency treatment should be done to win control of seizures in the shortest time, in the selection of anti-arrhythmia disorder drugs, it should also make preparations for direct current synchronized cardioversion,[link widoczny dla zalogowanych], who should be accompanied by shock and necessary cause of anti-shock treatment.
