Objective To investigate the effect of ECG characteristic and clinical prognosis of ventricular electrical storm (VES) in patients with hypertrophy and acute myocardial infarction (AMI).
Methods 317 cases of VES in patients with hypertrophy and AMI group. Sixty cases of after AMI patients non-VES group. The analysed of ECG examination and keep watch on ECG was relationship between clinical features and prognosis among the two groups.
Results In VES group PTFv1 abnormal, ∑ST segment elevation amplitude, ST segment elevation leads, ST segment reduction amplitude leads, QTc interval prolongations, Left ventricular hypertrophy. The coronary arteries on complete close up anterior wall or complicated anterior more control of wall AMI and LAD merge LCX or RCA was significantly increased (p<0.05–0.01). Clinically occurrence of complications such as pump failure, infarct extension, angina pectoris, malignant arrhy mortality ventricular electrical storm 6 h after AMI was obviously increased (p<0.05–0.01).
Conclusion For those after hypertrophy and AMI patients with VES who having abnormal ECG indexes, clinical shortterm prognosis was poor. Comprehensive measures should be taken to improve prognosis.
