Our study gives a solid evidence of impairment of median nerve conduction defect
of both sensory and motor component.
Key Words: Coronary artery disease, Chronic conduction defect
, Coronary angiography, Permanent pacemaker
Extreme caution and close monitoring for development of heart block are needed after initiation of ticagrelor, especially in patients with preexisting conduction defect
or on AV nodal blocking agent.
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.
Boxer Cardiomyopathy, or more specifically arrhythmogenic right ventricular cardiomyopathy (ARVC), is an inherited electrical conduction defect
that causes an arrhythmia, or irregular heart beat.

After eighteen hours the hospital's ward coordinator reminded him that the patient had not shown any dizziness since admission and the monitor had not indicated a significant conduction defect
, and so the patient should be sent home.
Naturally occurring mutations in LMNA have been shown to be responsible for distinct diseases called laminopathies, including dilated cardiomyopathy with of without conduction defect
and with and without variable skeletal muscle involvement (17-19, 4, 20).
The SCN5A gene governs the behavior of cardiac sodium ion channels, and mutations in the gene are known to cause long QT syndrome, Brugada syndrome, sudden unexplained nocturnal death syndrome, ventricular fibrillation, congenital sick sinus syndrome, and progressive cardiac conduction defect
. "Most SCN5A mutations causing arrhythmia produce channels that continue to operate late in the cardiac cycle when normal channels are silent; such late activity is a substrate for chaotic rhythms and sudden death," the investigators said (J.
In pretreatment studies, the Wisconsin scientists pinpointed the patients' tachycardia to a specific conduction defect
in the electrical impulses that cause the heart's lower chambers to contract.
It may lead to central nervous system dysfunction; confusion, convulsions, coma, reversible cardiac conduction defect
, secondary renal insufficiency even death.
