Background: Alcoholism is seldom detected among emergency room outpatients, which is attributed to the non-adoption of diagnostic routines, to the difficulty of doing a special anamnesis for diagnosing alcoholism, and to the lack of sensitivity and specificity of the laboratory tests. This study has the purpose to determine whether the CAGE assay (composed by 4 questions of easy memorization) is able to supply this difficulty in detecting alcoholism.

Material And Methods: We did a transversal study with consecutive sampling among outpatients of the Internal Medicine Department at Cajuru University Hospital emergency room.

Contrast echocardiography was used before cardiac catheterisation in 37 patients with atrial septal defect and a left-to-right shunt and in 18 patients with a raised right atrial and ventricular pressure to assess the contrast echo effect in the inferior vena cava. Using two dimensional contrast apical echocardiography we found a negative contrast echo effect within the right atrium in many but not all patients with atrial defect. Contrast echoes entering the inferior vena cava during presystole or early to mid-diastole were detected in patients with heart disease causing raised right atrial and ventricular pressures and also in all patients with atrial septal defect.

Echocardiography was used in 40 patients with atrial septal defect (ASD), diagnosed by cardiac catheterization. A dilated right ventricle and abnormal interventricular septal motion were observed at M-mode echocardiography in patients with large L-R shunt. The two-dimensional apical four chamber view was reliable to detect the ostium primum type but not the secundum type of ASD.

Linear contrast echo configuration on the pulmonary valve M-mode echogram was assessed in 28 patients with pulmonary hypertension, in 10 with pulmonary regurgitation, and in 10 normal subjects. Contrast echo parallel lines filling the total systolic phase of the pulmonary valve were recorded in normal subjects. Contrast echo lines stopping in early systole around the pulmonary valve mid-systolic notch were seen in all the patients with pulmonary hypertension in relation to changes with the pulmonary flow.

We studied by cineangiography and standard and subxiphoid echocardiography the left ventricular wall motion in 50 patients with old myocardial infarction and 10 normal subjects. Coronary artery angiography showed a good correlation with the electrocardiographic site of infarction and with the asynergic areas detected by cineventriculographic examination and bidimensional echocardiography. From the correlation of data related to the asynergic areas detected by angiographic and echocardiographic methods it was possible to establish that subxiphoid approach allows to visualize the posterior-lateral wall whereas the parasternal approach the posterior-inferior wall of the left ventricle.

M-mode and two-dimensional subcostal contrast echocardiography were used in 67 patients and 10 normal subjects to evaluate the contrast echo effect on the inferior vena cava echogram in relation to the cardiac cycle and respiratory events. No contrast echoes were recorded in the inferior vena cava in normals during normal breathing. Contrast echoes were recorded entering the inferior vena cava in systole in 20 patients with tricuspid regurgitation and in pre-systole in patients with atrial septal defect and left-to-right shunt and in some of the patients with elevated right atrial and ventricular end-diastolic pressure.

According to a recent national survey, 387 patients were treated by permanent pacing in 10 Italian centers, between 1961 and 1966. Of these patients 205 have died; 131 (77 males and 54 females) are still alive and no informations could be obtained for the remaining 51 (13%). The overall survival of patients treated during this period of time is therefore not less than 34% which is comparable to that of general population of the same age group.

Eight patients with ventricular tachycardia (VT) have been studied by unipolar recordings of 7 endocardial points of the left ventricle (LV) and 6 endocardial points of the right ventricle (RV) in order to record if possible: 1) where the VT arose; 2) a continuous electrical activity during the sistodiastolic phase of the intracardiac ECG [late potentials (LP)], suggesting the reciprocating mechanism of VT. All the patients underwent cardiac catheterization with left and/or right ventriculography. A coronary arteriography was performed in four cases.

To obtain information on normal left ventricular activation, endocardial recordings with an electrode catheter were made a seven left ventricular sites in ten patients undergoing diagnostic heart catheterization. All the patients had: 1) sinus rhythm; 2) normal duration and shape of the QRS complex of left chest leads; 3) normal left ventriculography, i.e.

To obtain information on endocardial activation-sequence, unipolar recordings at seven left ventricular and six right ventricular points were performed in a 37-year-old man suffering from cardiomyopathy and tachycardia-dependent left bundle branch block (LBBB). Results were as follows: 1) the recovery time was longer in anterior than in posterior portion of left bundle branch fibers; 2) an high posterior left ventricular point was directly activated via posterior left bundle branch fibers; 3) the directly activated left ventricular zone was too small and relatively too late excited in respect of the right interventricular septum, from which the stimulus reached the left septum, to mask the LBBB electrocardiographic pattern; 4) in the presence of tachycardia-dependent LBBB the duration of left ventricular endocardial activation was about twice (62 msec) that found in the absence of tachycardia-dependent LBBB (28 msec).
