==Overview==
Intraventricular conduction delays (IVCD) are abnormal [[ECG]] pattern, which may or may not be associated with symptoms.  Complete history to find out underlying cardiac condition would be the best approach in asymptomatic patients.
 
==History and Symptoms==
The following history should be elicited while evaluating a case of intraventricular conduction delay :
* History of [[palpitations]], decreased general activity, [[fatigue]], reduced exercise tolerance, [[dizziness]] and [[syncope]]
* Family history of [[ventricular arrhythmia]]s, [[sudden cardiac death]], [[heart block]]s and [[myocardial infarction]]
* History of cardiac surgery
* Past history of myocardial infarction, [[myocarditis]], [[cardiomyopathy]] and [[hypertension]]
* History of congenital heart disease in case of children

Patients with isolated BBB without underlying heart diseases are usually asymptomatic.  Such people do not require further diagnostic evaluation.   In patients with underlying heart disease symptoms are usually due to the heart disease rather than IVCD's itself.  Such symptoms include:
* [[Palpitation]]s
* [[Fatigue]]
* [[Presyncope]]
* [[Syncope]]
* Reduced exercise tolerance
