Myocardial Stunning After Electrocution With Complete Reversibility Within 24 Hours: Role of Repeat Transthoracic Echocardiograms in Potential Cardiac Transplant Donors

Figures

Figure 1.
Figure 1. EKG showed sinus tachycardia with no ST or T-wave changes suggestive of ischemia.
Figure 2.
Figure 2. CXR showed mild pulmonary congestion.
Figure 3.
Figure 3. Transthoracic echocardiogram showing severely depressed left ventricular systolic function with an ejection fraction of 20%.
Figure 4.
Figure 4. Transthoracic echocardiogram done after 24 h showing completely normal left ventricular systolic function with an ejection fraction of 55-60%.
Figure 5.
Figure 5. Coronary angiography evaluating patient’s coronary anatomy which was normal.
