The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been reported to cause cardiac complications including myocarditis, myocardial infarction (AMI) and various tachyarrhythmias. We present a 63-year-old male who developed nonreversible symptomatic bradycardia due advanced atrioventricular block (AV) requiring pacemaker placement in the setting of SARS-CoV-2 pneumonia.

Thirteen patients with complete atrioventricular block resulting from coronary disease were studied. In seven the diagnosis of coronary disease was established by the presence of typical history and electrocardiographic and enzymatic findings compatible with an acute infarction. Of the remaining six cases, three had a typical history of angina pectoris. In three cases there was no history of my...

no H potential or by a prolonged AH interval, indicating concealed retrograde penetration of the His bundle. Thefact that retrograde conductionaffectedanterograde conduction indicates that the anterogradeandretrograde pathways are not totally independent. Atropine significantly improved retrograde conduction; this suggests that the retrograde conduction occurs through the conduction system in a...

Sinus of Valsalva aneurysm is a rare cardiac anomaly with wide spectrum of clinical presentation ranging from asymptomatic state to dreadful complications due to compression of vital surrounding structures or aortic dissection. There are only few reported cases of sinus of Valsalva aneurysm presented with cardiac arrhythmias including complete heart block. We herein, present a case of a 50 year...

Six children, aged between 3 and 19 years, with congenital complete heart block without associated cardiac disease were studied by His bundle electrography. All were symptomatic with resting ventricular rates over 40 beats/min, and electrocardiograms that showed a normal axis and QRS complex. His bundle to ventricular activation was within the normal range in all and the block was proximal to t...

BACKGROUND First and second-degree heart blocks are partly common rhythm disorders in thalassemic patients but complete heart block is a very rare complication of iron overload cardiomyopathy. CASE PRESENTATION This 15-year-old boy, a known case of major β-thalassemia was admitted to our emergency unit with dyspnea and cough because of decompensated heart failure. The electrocardiogram showed...

A 26 years old male presented with vertigo and history of fall. The electrocardiogram revealed 2:1 second-degree heart block and later progression to complete heart block. Transthoracic echocardiography revealed aneurysm at the site of ascending aorta and computed tomographic scan showed an aneurysm of right sinsus of Valsalva extending into right atrioventricular and interventricular groove an...
