Each of these two pathologies, AF and LVH, can impose negative hemodynamic effects on the car-diac function. Case: We present a case of a patient with AF, TWI and long standing HTN that went into post-operative pulmonary edema. Conclusion: Even returning to base line poorly controlled hypertension, and even more so during a hypertensive cri-sis, their concurrent presence may inflict even more detrimental effect manifested by elevation of pulmonary venous pressure and pulmonary edema.展开更多

Methods 105 consecutive patients with Q-wave anterior wall MI were enrolled in this study. These patients were divided into two groups according to the polarity of T wave at 6 months: negative T - wave group (n=45) and positive T-wave group (n = 60) . Electrocardiograms were recorded and echocardiogra-phy was performed on admission and at 6 months after anterior MI. Results The peak serum creatine ki-nase activity of negative T - wave group and positive T -wave group was (4158 ±2478) IU/L and (2868±2358) IU/L, respectively (P < 0. 05). Left ventricular function was better in positive T - wave group than negative T - wave group. Conclusion Earlier normalization of the precordial T waves was associated with greater improvement in LV function. The early presence of inverted T waves in leads with abnormal Q waves can be used to assess the degree of LV dysfunction.展开更多

All subjects, as part of standard preparticipation screening medical evaluation, underwent a basal and post step test 12-lead electrocardiogram(ECG). The athletes with abnormal T-wave flattening and/or inversion were considered for an echocardiogram evaluation and an incremental maximal exercise test on a cycle ergometer. Arterial blood pressure and heart rate, during and after exercise, were also measured.RESULTS Twenty-one of the 316 subjects(6.9%) showed false tendons in the left ventricle. The majority of false tendons(52.38%) were localized between the middle segments of the inferior septum and the lateral wall, 19.06% between the distal segments of the septum and the lateral wall, in 5 subjects between the middle segments of the anterior and inferior walls, and in one subject between the middle segments of the anterior septum and the posterior wall. ECG abnormalities, represented by alterations of ventricular repolarization, were found in 11 subjects(52.38%), 90% of these anomalies were T wave abnormalities from V1 to V3. These anomalies disappeared with an increasing heart rate following the three minute step test as well as during the execution of the maximal exercise.CONCLUSION Left ventricular false tendons are frequently localized between the middle segments of the inferior septum and the lateral wall and are statistically associated with ventricular repolarization abnormalities.展开更多
