EVALUATION OF MID-SYSTOLIC-CLICK SYNDROME ― with special reference to its apexcardiogram and left ventricular systolic time intervals ―
Clinical and polycardiographic observations conducted on 21 cases with mid-systolic-click syndrome showed the following results. This syndrome was seen mostly in lean, young women, and most of them came to the hospital with complaint of palpitation. In addition, more than half of these cases had a past history of arrhythmia. Polycardiographically, the left ventricular function was maintained at normal level in most of the cases. Some form of“retraction”could be recognized on the apexcardiogram, and its nadir almost always coincided with the click. For the early detection of this syndrome careful auscultation at bedside and apexcardiography may serve as useful diagnostic aids.
