Portable CPS Increases STEMI Survival
Figure 1
The first patient was a 59-year-old male in good health except for hypertension treated with atenolol. He developed severe anterior chest pain and called 9-1-1. During transport to Sharp Memorial Hospital, he developed v fib arrest. EMS providers started ALS and continued throughout the transport. See the ECG on presentation to the ED.
Figure 2
Despite the administration of antiarrhythmic drugs and electric shock, a stable cardiac rhythm couldn’t be maintained until CPS therapy was instituted. An ECG obtained after placement of CPS demonstrated sinus rhythm with changes of an acute anterior wall myocardial infarction.
Figure 3
Following stabilization, the patient was taken to the cardiac catheterization lab, where coronary angiography demonstrated a sub-total occlusion of the left anterior descending coronary artery.
Figure 4
Following placement of a coronary stent, the left anterior descending artery (LAD) was opened.
Figure 5
A subsequent ECG demonstrated marked resolution of the ST elevation.
Figure 6
While being evaluated by an ED physician, he developed v fib arrest.
Figure 7
CPR, IV amiodarone and dozens of defibrillatory shocks restored sinus rhythm for only brief periods of time. An ECG recorded during a brief period of sinus rhythm was consistent with acute inferior wall infarction.

Figure 10
Following successful PCI, the patient’s cardiac rhythm remained normal and the ST elevation resolved. Left ventricular function by echo was normal at discharge, and the patient suffered no apparent neurological injury. However, surgical repair of the sternum was required due to prolonged CPR. This post PCI ECG shows resolution of inferior ST elevation and anterior ST depression.
