Oxyen consumption of surgical patients was measured by McKesson Metabolar (Model 185) on the Recording Metabolar Chart (M-147) in four groups: group A, at resting state immediately before preanesthetic medication; group B, immediately following induction of anesthesia with thiopental (10 mg./kg.); group C. 30 minutes after surgical ether anesthesia; and group D, when conciousness returned during the stay in the recovery room. The results are as follows: (1) Thiopental reduced oxygen consumtion by 25 per cent. (2) Ether anesthesia reduced, oxygen consumption by 59 per cent. (3) During recovery from anesthesia, oxygen consumption was 28 per cent below the control. (4) Comparing with other data, ether anesthesia reduced oxygen consumption significantly more than fluothane or nitrous oxide did.

Successful percutaneous transluminal angioplasty (PTA) of an internal mammary artery graft was performed in a 40 year old male patient who had recurrent angina soon after bypass surgery. Coronary angiography showed total occlusion of proximal portion of the left anterior descending artery and normal right coronary artery. Angiography of the left internal mammary artery graft revealed a tight stenosis (90% diameter narrowing) in the mammary artery at its insection into the left anterior descending artery.Angiography after the angioplasty demonstrated a widely patent graft (residual stenosis 10%) and translesional pressure gradient was 10 mmHg.

High output heart failure due to congenital arteriovenous fistula is a rare disease and is difficult to treat. A 27 year old man, suffering from dyspnea, palpitation, lower extremity edema, and abdominal distension admitted May, 1987. At admission there were continuous thrill and bruit at left supraclavicular and infraclavicular area. The heart sound was irregular and rapid, and grade IV/VI pansystolic murmur was audible at the apex. Chest PA showed marked cardiomegaly with pleural effusion and notching at superior aspect of left 2nd rib. Selective left subclavian artery angiogram showed extensive congenital arteriovenous fistula at the area of left subclavian artery and its branches. After setrial feeding artery embolization and palliative operation, the fistula size decreased much with clinical improvement.

Myocardial infarction is almost regularly associated with severe and widespread obstructive coronary artery disease. Recently, there have been some reports of myocardial infarction with normal of near normal coronary arteries on cineangiography. The following report concerns 6 cases (4% of a series of 142 consecutively studied patients with myocardial infarction) of myocardial infarction proved on clinical grounds with normal or near normal coronary arteries at coronary angiography obtained several months later. The clinical data was shown in Table 1 and Table 2. All 6 patients were male. Three were in the fifth, two in the sixth, and one in the seventh decade. Multiple risk factors were present in only one patient. Areas of localized dyskinesia or hypokinesia were demonstrated in five on the left ventricular cineangiography. The left ventricular end-diastolic pressure was greater than 12 mmHg in all 6 patients. One patient had hypertrophic cardiomyopathy and the remaining 5 patients had no underlying heart diseases. One patient had moderate congestive heart tailure. It is possible that prolonged, localized coronary artery spasm or platelet thrombi that subsequently resolved are a part of the pathogenic mechanism.

Higenamine is known to possess stimulatory activity on beta-receptor of the heart. Chronotropic actions of higenamic were studied in spontaneously beating right atrial muscle isolated from rabbits. The frequency of spontaneous beating and the relative threshold voltage of the right atrium were examined. The relative threshold voltage was defined as the minimal voltage of the given impulse above which the right atrium could be paced at the frequency of 20% of higenamine was also observed. Higenamine caused the postive chronotropic effect. This response became prominent as the ca2+ concentration in the bathing solution lowered. When tetrodotoxin was added to the bathing solution, the effect of higenemine altered and became similar to that of epinephrine. Higenamine reduced the relative threshold voltage of the right atrium in the bathing solution with [ca2+] of 0.5mM. Such effect was abolished by tetrodotoxin. The effects of verapamill on the spontaneous rate and the relativel threshold voltage were inhibited by higenemine. The above results suggest that, aithough the main action og higenamine is on the Ca channel, higenamine also have a minor effect of augmenting the Na channel.

Conventional dual chamber pacing (DDD) preserves atrioventricular synchrony but depend on appropriate sinus node function to achieve physiological heart rate with exercise by atrial tracking. Other indirect indicators of metabolic demand have been used to modulate pacing rate increases with exercise including sensing of pH, respiratory rate, ventricular repolarization and oxygen saturation. The activity sensing approach is unique in that noise generated by activity modulates the response and empirical programming of the unit allows for attaining the desired rate for a given level of activity. Physiologic rate increases can be obtained in patients with sinus node dysfunction or even atrial fibrillation. The lead can either be positoned in the atria for patients without atrial fibrillation or AV conduction disturbance or in the ventricle. We present two cases of rate responsive pacing using the Activitrax.
