The patient developed second degree atrioventricular heart block throughout the study, most notably in phasic REM sleep and persisted during the titration, although with improvement once on appropriate PAP settings. Consequently, a 24-hour Holter ECG was recorded showing sinus rhythm with intermittent ...
He had a history of left bundle branch block (LBBB) on electrocardiography (ECG). His medications included carvedilol, aspirin, clopidogrel, and lovastatin. In the emergency department, his ECG showed first-degree heart block and LBBB, and telemetry showed atrioventricular (AV) Wenckebach (ie, ...
Answer to: How does the ECG vary and what is occurring during these conditions: junctional rhythm, second degree heart block and ventricular...
However, the function of the atrial pacemaker is usually normal and the degree by which the heart rate slows down is often modest. Here we report the case of a 20 year old male Caucasian with severe overt hypothyroidism. He presented with syncopation due to second degree atrioventricular block...

An ECG rhythm strip shows a regular ventricular rhythm at a rate of 30 beats/min, more P waves than QRS complexes (the P waves occur regularly), a variable PR interval, and a QRS duration of 0.14 second. This rhythm is ___. third-degree AV block Transcutaneous pacing is the treatment...
Two to one AVB or higher degrees of AVB cannot be classified into Wenckebach type I or Mobitz type II AVB. A common mistake is to equate 2:1 and higher degree of AVB with type II infranodal block when block can be either in the AV node or the His-Purkinje system. ...
Which of the following is an example of an atrial tachycardia? a) Atrial flutter b) First-degree heart block c) Respiratory sinus arrhythmia d) Sinus rhythm Discuss factors that regulate cardiac output. What does the right coronary artery arise from?
Fill in the blank: Normally, the ST segment on an ECG measures ___ second or less. How does the ECG vary and what is occurring during these conditions: junctional rhythm, second degree heart block and ventricular fibrillation? Fill in t...
