Risk factors for acute myocardial infarction (34 cases)

Sudden death of people before and after ECG Notes: CRBBBe complete right branch conduction resistance Cambodia fine, CLBBB, coriander whole of the left branch block I_vB Cambodian complete atrioventricular block induced by factors of 1.3 patients 34 cases of sudden death,[link widoczny dla zalogowanych], due to emotional should be (mental stimulation, fear, anger,[link widoczny dla zalogowanych], tension, etc.) and 23 cases of sudden death due to force i (urine, excessive early activity, etc.) in 5 cases 6 cases of the above factors} meal often exist in varying degrees. 1.4 Prognosis of 34 cases, 12 cases of successful resuscitation by the rescue, accounting for 35.29. 22 cases of death, accounting for 9 of the total number of AMI patients. O9. Death of patients, sudden death more than before the existence of severe arrhythmia and abnormal ECG changes more than other magazines rehabilitation and convalescent 9 volumes change, see the attached table. 2 AMI patients to discuss their emotional and behavioral outcomes of more attention. In the main symptoms and signs had no significant difference in conditions, the availability of emotional stress, that anxiety (mental stress, fear, irritability, despair,[link widoczny dla zalogowanych], anxiety, insomnia, not Taiwan as, mood fluctuations), and depression, can directly affect the patient's condition, sT elevation level and time, cardiac arrhythmia, complications and mortality. Reported in the literature, these two factors on the availability of comparison, AMI patient mortality were 53 and 3.7. . The group, mood changes (mental stimulation, fear, anger, tension, etc.) in 23 cases, accounting for 67.64 consistent with those reported. . Mood changes, meal, improper force or activity to promote the body sympathetic nerve activity, catecholamine release, further increase of myocardial ischemia and hypoxia, increased self-regulation of myocardial cells, decreasing the value of ventricular fibrillation induced ventricular fibrillation Court. Therefore,[link widoczny dla zalogowanych], we should strengthen the physical and psychological care for AMI patients,[link widoczny dla zalogowanych], relieve their tension and anxiety. After onset of myocardial infarction declined 3 ~ 5d should visit, absolute bed rest, maintain smooth stool. The patients physical and mental quiet is important to the prevention of sudden death. In recent years, judging from the extent of abnormal ECG changes in the prognosis of AMI patients have been reported 72h after the onset of AMI patients electrocardiogram observed. ECG abnormalities more, the higher the mortality. 5 or more abnormalities of 66.66, and only AMI change, not associated with mortality of other ECG abnormalities only 3.75. . ECG before sudden death was complete left bundle branch block or right bundle branch {inferior myocardial infarction with precordial sT-segment depression ≥ 2mV 'forehead, multi-source or in pairs in the atrial, ventricular premature beats is a dangerous The clinical signs of AMI patients should be regarded as a predictor of sudden death in the near future. . literatures, the death of 42 patients had QT interval prolongation., so that the QT interval prolongation and sudden death is a warning signal AMI patients. The group of 12 patients with sudden death, QT interval prolongation down, accounting for 3529. recently reported in the literature, ECG QT dispersion in AMI patients, the QTd (longest lead from different minus the shortest QT interval QT interval) prolongation of a positive correlation with the occurrence of ventricular fibrillation, QTd ≤ 60ms had no ventricular fibrillation occurred} 60ms <QTd <100ms were occurrence of ventricular fibrillation 42.86 i00 I ≥ 100ms by ventricular fibrillation occurred. The mechanism may be myocardial infarction. infarcted and normal myocardium in acute myocardial ischemia between the district, due to acute ischemia and lead to calcium mobilization and intracellular potassium ion concentration changes and sympathetic innervation of balance, so that lower ventricular fibrillation threshold, easy to extend the period of chatter, increased self-discipline Purkinje fibers, conduction velocity. ischemic myocardium accompanied by cell transmembrane action potential phase 3 repolarization delay.
