Delayed intraventricular conduction is a common abnormality detected on the electrocardiogram (ECG). Intraventricular conduction delay (IVCD) may manifest as right bundle branch block (RBBB), left bundle branch block (LBBB), nonspecific IVCD, left anterior fascicular block (LAFB), or left posterior...

Result: Here, we report on a 13-year-old girl who was diagnosed of nonspecific intraventricular conduction delay (QRS duration 120 ms) with noninfarct Q waves in the inferior leads in the ECG which was part of the routine cardiac examination before starting psychotropic drug therapy due to ...
Podrid, MD. Discussion There is a regular rhythm at a rate of 62 beats/min. A P wave occurs before each QRS complex (+), and the P wave is positive in leads I, II, aVF, and V4-V6. This is a normal sinus rhythm. The PR intervals are not constant. The PR intervals of complexe...
Intraventricular conduction delay: QRS > 100 ms in lead II Terminal R wave> 3 mm in aVR or R/S ratio > 0.7 in aVR The right-sided intraventricular conducting system is more susceptible to the effects of sodium channel blockade — this causes terminal right axis deviation of the QRS complex...
This frequently appears as “non-specific intraventricular conduction delay,” characterized by a widened QRS complex of greater than 120 milliseconds that does not meet the criteria for a left or right bundle branch block. Frequently, an IVCD will look like a LBBB in lead V1 with a rS ...

not always reliable [7]. Computers also can’t tell why intervals are abnormal or integrate multiple abnormalities: for example, prolonged PR and QRS intervals and peaked T waves from life-threateninghyperkalemiamight be labeled ‘first degree AV block” and “non-specific intraventricular delay.”...

J waves are often seen in young males with no apparent structural heart diseases, whereas intraventricular conduction delay is often observed in older individuals or those with a history of myocardial infarction or cardiomyopathy [5, 7]. J wave is mixed in the normal ST segment, coupled with ...
