WE STUDIED 102 PATIENTS. ALL PATIENTS HAD A CHEST ROENTGENOGRAM AND A MEASUREMENT OF BLOOD GASES WHILE IN 94 PATIENTS A ECHOCARDIOGRAM WAS ALSO PERFORMED. THE CHEST ROENTGENOGRAMS WERE ANALYZED WITH THE USE OF A 0-16 POINTS SCORING SYSTEM. WE CONCLUDED THAT THE "QUANTITATIVE" ANALYSIS OF CHEST ROENTGENOGRAMS WITH THE USE OF THIS PARTICULAR SCORING SYSTEM COULD TURN OUT TO BE A PRACTICAL, RELIABLE AND REPRODUCIBLE METHOD IN ASSESSING THE SEVERITY OF HEART FAILURE

The ECG showed narrow QRS complex tachycardia at a rate of 300 beats/min and downsloping ST-segment depression. Following intravenous administration of adenosine, atrial flutter was confirmed and due to hemodynamic instability a direct current shock was delivered which restored sinus rhythm. The causes of such rapid ventricular rates in atrial flutter are discussed a propos with this case report.

Two hundred twenty-three (172 men and 51 women) non-diabetic patients with acute myocardial infarction were studied prospectively. The main outcome measures of the study were based on a comparison of in-hospital mortality and major non-fatal in-hospital events (pulmonary edema, post-infarction angina, infarct extension, mechanical complications, conduction disturbances and ventricular arrhythmias) between microalbuminuric and normoalbuminuric patients. A significant proportion of patients (33.6%) had microalbuminuria. Seventy-six patients (34%) developed an in-hospital event (fatal or non-fatal). Six patients (2.7%) with acute myocardial infarction died in the hospital. Patients with microalbuminuria had a higher mortality rate in comparison with normoalbuminuric patients (6.6% vs. 0.68%, p = 0.01). For non-fatal events, the incidence of pulmonary edema and ventricular arrhythmias was significantly higher in patients with microalbuminuria (14.6% vs. 3.4%, p < 0.001 and 12% vs. 3.4%, p = 0.01, respectively). The combined end-point of the total number of fatal and non-fatal events was significantly higher in patients with microalbuminuria (57.3% vs. 22.3%, p < 0.001). In multiple logistic regression analysis, microalbuminuria (p < 0.001) and ejection fraction (p = 0.01) were independently related to the occurrence of major in-hospital events. Microalbuminuria is a significant predictor of in-hospital morbidity and mortality in non-diabetic patients with acute myocardial infarction.

On evaluation, she developed a new onset sustained ventricular tachycardia (VT) and the diagnosis was confirmed through genetic testing, cardiac imaging, and electrophysiological study. Insertion of automatic implantable cardioverter defibrillator (AICD), antiarrhythmic medication, and ventricular ectopy radiofrequency ablation afforded improvement of symptoms. In conclusion, combination of these treatment modalities abated ventricular tachycardia from ARVC.

Our patient experienced a severe retrosternal pain of abrupt onset during the DSE study, whereas EKG was evident of significant ST segment elevation in II, III, avF, and V5-V6 leads, followed by an accelerated idioventricular rhythm. Immediate coronary angiogram revealed a minor dissection of the distal part of the right coronary artery.

At a repeat procedure, this time in our hospital, cannulation was attempted, and finally achieved, albeit with difficulty, of the middle cardiac vein and the pacing lead was successfully placed at an apical posterolateral position. Pacing and sensing thresholds were excellent. This strategy obviated open thoracotomy for lead placement which would otherwise have been the only option available.

Ventricular tachyarrhythmias were induced at an electrophysiology study and the patient received an implantable defibrillator.
