Dual Conduction and SVT
Report: Sinus rhythm Dual PR interval: 0.14â and 0.30â Comment: The two PR intervals alternated over periods of minutes, finally attracting the attention of the ICU night staff. Unfortunately, no spontaneous change was recorded. In the morning, I g
Möbitz 2 Block
Report: Sinus rhythm Second degree AV block, Möbitz 2 Right bundle branch block Comment: The conducted P waves show no increment in their PR intervals prior to the blocked one - a clear-cut case of Möbitz 2 block. Typically, the QRS itself is prolong
