In the index case, we noted intraventricular conduction
defect manifesting as slurring of QRS in chest leads III and aVL.
Despite treatment with high-dose glucocorticoids, she developed intraventricular conduction
delay within 24 hours, followed by complete heart block.
Patients with atrioventricular or intraventricular conduction
defects on electrocardiogram (ECG), left ventricular (LV) ejection fraction (EF) <50%, significant valvular abnormalities, history of coronary artery disease, suspicion of secondary HT, history of diabetes mellitus, thyroid disorders, pulmonary diseases, and renal failure, electrolyte imbalance, technically insufficient echocardiographic and ECG data were excluded.
Echocardiography (ECG) shows different changes in the form of sinus tachycardia, bundle branch blocks, intraventricular conduction
defect, atrial and ventricular premature complexes, atrial fibrillation, ventricular tachyarrhythmia, ST segment elevation or depression, and T wave inversion.

Sample electrocardiograms point out the wave shapes and intervals for diagnosing coronary artery disease, intraventricular conduction
defects, atrial rhythm disorders, ventricular tachycardias, sinus node dysfunction, and atrioventricular block.
A narrow complex tachycardia or supraventricular tachycardia usually has a QRS duration of <120 ms, unless there is bundle branch block or an intraventricular conduction
3) In this article, we will review the pathophysiology, diagnosis, prognosis, and treatment options of AV blocks versus intraventricular conduction
blocks these rhythm disorders.
Supernormality of A-V and intraventricular conduction
and ventricular parasystole under the influence of epinephrine.
The intraventricular conduction
system of the left ventricle is composed of fibers of the bundle of His that become the main left bundle branch and then divide into anterior and posterior fascicles, further branching to become the distal conduction system.
Electrocardiogram (ECG) revealed sinus rhythm and prominent intraventricular conduction
delay (QRS: 160 msn) which was normal except strain pattern at the age of 10 years (Fig.
Hypermagnesaemia is uncommon unless iatrogenic but can be associated with delays in AV and intraventricular conduction
