The syndrome associated with midsystolic click and late systolic murmur

Paroxysmal Ventricular Fibrillation in Two Patients with Hypomagnesemia

“…In both patients prolongation of the Q-T interval was a prominent electrocardiographic feature. Others12 17,37,38 have noted association between a prolonged Q-T interval and ventricular arrhythmias, but no single mechanism satisfactorily explains these observations. In the absence of overt hypokalemia or hypocalcemia, a prolonged Q-T interval might be explained by abnormalities in the relationship between intracellular and extracellular potassium.…”

Mitral valve prolapse and partial syndactyly of the hands

“…In addition to MVP, our patient had partial syndactyly of both hands which prevented radial flexion of the wrist. This has not been described before in large reviews of this syndrome (Devereux et al, 1976;Engel and Hickman, 1980;Gibney and Maurer, 1980;Hancock and Cohn, 1966;leresaty,1973, 1979Udoshi et al, 1979) .…”

“…Defecation syncope is a possibility, as is a postmicturition event, but those diagnoses typically are described in different patient populations (Pathy, 1978). However, syncope has been described in patients with MVP, both with (Devereux et al, 1976;Hancock and Cohn, 1966;leresaty, 1973), and without arrhythmia (Devereux et al, 1976). In addition to MVP, our patient had partial syndactyly of both hands which prevented radial flexion of the wrist.…”

An interpretation - mitral valve prolapse syndrome

“…The electrocardiogram may show ventricular repolarization alterations, especially in the inferior derivatives (leads) 19 . Patients might have arrhythmias 20,21 , stretching of the QT segment and its greater dispersion (spread) 22,23 . Late potentials may exist 24,25 .…”

“…It is improbable that only the mechanical phenomena, the exaggerated movement of the leaflets, can explain it 15,23 .…”
