RÉSUMÉ
Cardiogenic shock [CC] is the most common cause of death in acute myocardial infarction [MI] and it has been often associated with fatal evolution. The aim of this study is to emphasize the positive impact of myocardial revascularisation especially percutaneous coronary angioplasty [PTCA] on short and mid term survival of 35 patients hospitalized for acute MI with CC. All the 11 patients who were on conventional therapy died, whereas the hospital mortality rate of the 24 patients who underwent primary PTCA was 41 percent. PTCA in CC complicating MI is highly effective and reduces the mortality rate in the literature from 80 percent to 40 percent for this reason PTCA should be performed in each case of MI with CC seen in the first 6 hours

Decreased heart rate variability after myocardial infarction [MI] was demonstrated to be highly correlated with cardiac sudden death. The assessment of HRVA was performed in 100 consecutive patients hospitalized for acute myocardial infarction [AMI] in Tunis Military Hospital between September 94 and july 96 with a mean follow up of 28 months. HRVA was evaluated within 8 to 10 days after hospitalization. A group of 62 patients without AMI was used as control group. The comparison of components of HRVA in time and frequency dmain demonstrated significant differences between the two groups. Significant differences were also seen between the subgroup of patients who died suddenly during follow up and the subgroup of survivors. The assessment of HRVA must be one of the non invasive prognostic variables after MI to evaluate the risk of cardiac sudden death

Simultaneous tachycardia is not a frequent arrythmia and its diagnosis has been improved by invasive and noninvasive techniques of recording atrial activity. Thanks to 3 cases of simultaneous tachycardia collected over 10 years of activity and, a review of the litterature on the subject the authors try to emphasize the main characteristics of this arrythmia. Simultaneous tachycardia has major electrocardiographic polymorphism, nevertheless the typical ECG feature is irregular tachycardia with wide QRS and frequent modifications of the QRS morphology. The prognosis of this arrythmia seems to be enhancing and, amiodarone is a very effective drug in this case
