Atrial capture detection with endocardial electrodes.

A new method of evoked response detection, previously demonstrated in the ventricle, has been studied in the atrium at the time of routine pacemaker implant in 16 patients. The atrial evoked response was readily detectable in all patients due to excellent recovery from poststimulus polarization. In six patients, as experimental threshold-tracking pacemaker was used to automatically verify atrial capture and to generate strength-duration curves. It is concluded that this pacing technique is both simple and reliable, and that automatic atrial threshold tracking is feasible.

Peripartal cardiomyopathy.

A case of peripartal cardiomyopathy diagnosed post partum by preoperative routine examination for a sterilization operation is discussed. Data from the literature show that 50% of the patients suffering from peripartal cardiomyopathy recover nearly completely; the other patients with distinct symptoms of cardial insufficiency die almost without exception from the disease. Current concepts of diagnosis and treatment are reviewed.

Concomitant administration of timolol and hydrochlorothiazide/amiloride in hypertensive patients. Results of a titration study.

In an open dose titration study we evaluated the antihypertensive effect of the concomitant administration of timolol and hydrochlorothiazide/amiloride, administered on a b.i.d. basis. Twenty-eight out of 39 patients completed the study. Supine and standing systolic and diastolic blood pressures and pulse rate were significantly lower at the end of the titration period than at the end of the diuretic period.
