Atropine-Induced Ventricular Asystole During a Dobutamine Stress Test


Figure 1.
Figure 1. (a) Baseline ECG with NSR, LVH, and LAA, PR = 0.19 s. (b) ECG after second episode of third-degree AV block (PR = 0.22 s), which demonstrates new first-degree AVB. ECG: electrocardiogram; AVB: atrioventricular block; LVH: left ventricular hypertrophy; NSR: normal sinus rhythm.
Figure 2.
Figure 2. (a) ECG during DSE showing prolonging PR interval followed by complete heart block and ventricular asystole due to lack of escape rhythm. (b) Telemetry strip post-admission showing the same rhythm. ECG: electrocardiogram; DSE: dobutamine stress echocardiography.
