ECG Blue Belt online course: Learn to diagnose any rhythm problem. In addition to prolonged QRS duration, LBBB is characterized by deep and broad S-waves. A QRS duration of 120 ms (0.12 s) or more is required to diagnose a complete left bundle branch block. The hallmark of LBBB is the prolonged QRS duration. Idioventricular means relating to or affecting the cardiac ventricle alone and refers to any ectopic ventricular arrhythmia. ECG criteria for left bundle branch block (LBBB) It is easy to diagnose left bundle branch block (LBBB). ECG Yellow Belt online course : Become an ECG expert. Accelerated idioventricular rhythm is a ventricular rhythm with a rate of between 40 and 120 beats per minute.

It is a disturbance in the normal conduction of the electical impulses in the heart. At present, by means of electrophysiological investigations, one can verify and check 'in situ' the different forms and mechanisms through which rhythm and conduction disorders are manifested. AIVR, also known as Accelerated Ventricular Rhythm, results when the rate of an ectopic ventricular pacemaker exceeds that of the sinus node. IVCD stands for intraventricular conduction delay or disturbance. Abnormalities of local myocardial activation can further alter the specific pattern of venticular activation. The delay or blockage can occur on the pathway that sends electrical impulses either to the left. It sometimes makes it harder for the heart to pump blood to the rest of the body. On the other hand, the achievement of diagnostic decisions was of little importance outside the sphere of pure intellectual speculation since valid therapeutical treatments were lacking. An IVCD is the result of abnormal activation of the ventricles caused by conduction delay or block in one or more parts of the specialized conduction system (bundle of His, bundle branch or purkinje conduction system) resulting in widening of QRS complex. Bundle branch block is a condition in which there's a delay or blockage along the pathway that electrical impulses travel to make the heart beat. Only about ten years ago, the in terpretation of arrhythmias was obtained by a standard electrocardiogram to which experimental findings on animals were still arbitrarily applied. Even after thousands of years, research into the alterations of cardiac rhythm still holds a certain fascination, although modern methods and sophisticated devices have changed the approach to such studies. Undoubtedly the heart beat was, for a considerable time, the only semiological element by which man could interpret the dysfunctions of the organism. Atrial fibrillation/flutter, ventricular rate 138, nonspecific IVCD. IVCD is sometimes referred to as an incomplete bundle branch block. Defibrillation was per-formed immediately and sinus rhythm was restored. In the rhythm strip, the first two Pwaves are conducted with a markedly prolonged. intraventricular conduction delay: (ntr-vn-trk-lr), IVCD Abnormally slow conduction of electricity through the ventricular walls of the heart, resulting in a QRS complex on the electrocardiogram that lasts longer than 0.12 sec but less than 0.16 sec. Right afterwards, she went into ventricular fibrillation. Rhythm was the first expression of cardiac activity which fell under man's obser vation, and the heart beat has always represented the very essence of life itself as it accelerates or slows during moments of rest, effort, joy and pain until it comes to a halt at the moment of death. ECG strip showed wide complex tachycardia without obvi-ous P wave (Image 2) in view of patient’s unstable condi-tion, ventricular tachycardia was considered and synchro- nised cardioversion was performed.
