Ventricular tachycardia; prevalence and prognosis

Frequent or complex patterns of ventricular ectopic activity, whether occurring during routine activity or induced by exercise, are often a marker for serious heart disease and a harbinger of sudden death. The detection of such arrhythmias is thus an important responsibility of the physician. To find the prevalence, associated characteristics and prognostic significance of exercise induced non-sustained VT in a representative population. Nishtar Hospital, Multan. 1000 patients. Two years. Descriptive, analytical study. Convenient probability sampling done. Ten subjects, 7 men and 3 women, with exercise induced VT were identified, representing 1.1% of those tested; only 1 was young than 65 years. All episodes of VT were asymptomatic and non-sustained. In 9 of 10 subjects, VT developed at or near peak exercise. The longest run of VT was 6 beats; multiple runs of VT were present in 4 subjects. Two subjects had exercise induced ST segment depression, but subsequent exercise thallium scintigraphic results were negative in each. Compared with a group of age and sex matched control subjects. those with asymptomatic, non-sustained VT displayed no difference in exercise duration, maximal heart rate, or the prevalence of coronary risk factors or exercise induced ischemia as measured by electrocardiography and thallium scintigrahy. Over a mean follow period of 2 years, no subject has developed symptoms of heart disease or experienced syncope or sudden death. Thus, exercise induced VT in apparently healthy subjects occurs almost exclusively in the elderly, is limited to short, asymptomatic runs of 3 to 6 beats usually near peak exercise, and does not portend increased cardiovascular morbidity or mortality rates over a 2 year period of observation. Exercise induced VT in apparently healthy subjects occurs almost exclusively in the elderly, is limited to short, asymptomatic runs of 3 to 6 beats usually near peak exercise, and does not show increased cardiovascular morbidity or mortality rates over a 2 year period of observation

Measurement of serum cholesterol and triglyceride; evaluation in patients with diabetes; hypertension and cerebrovascular accident in south Punjab

Lipid disorders occur in patients with hypertension, cerebrovascular accident [CVA] and NIDDM. However their detection and subsequent intervention remains under-estimated throughout the world due to one or another reason. The aim of this study was to evaluate the status of lipids in our diabetic, hypertensive and stroke patients regardless of their hypertensive and glycemic control, age and sex. This study was carried out on 300 cases of diabetes mellitus, hypertension and cerebrovascular accident at Medical Unit-II of Nishtar Hospital, Multan. Out of 300 patients, 93 [31%] patients showed isolated stroke, 114 [38%] patients showed isolated diabetes mellitus. Isolated hypertension was found among 21 [7%], six [2%] patients out of 300 showed combined, hypertension, CVA and diabetes mellitus. 18% [6%] patients exhibited combined hypertension and stroke. 20 [6.7%] patients were having combined diabetes mellitus and Hypertension. 7 [2.3%] patients out of 300 exhibited combined diabetes mellitus and stroke

frequency of complications during heamodialysis

The commonly used renal replacement therapy for the end stage renal disease is the maintenance haemodialysis. Only 30% are having approach to renal transplantation, a gold standard treatment. The maintenance haemodialysis is the substitute for kidney functions. On one hand it is blessing for chronic renal failure patients, the complications may also occur on the other hand. This prospective study was conducted at Nephrology section of Medical Unit-II, Nishtar Hospital, Multan. The objective of the study was to determine the frequency of different complications during haemodialysis in patients having end stage renal disease. The patients with acute renal failure having haemodialysis were excluded from the study. The most frequently observed complications were depressive illness, vomiting, fever, itching and hypotension. The causative relations of the complications with other parameters were also assessed. Results indicate that predialysis, thorough work up of patients and certain steps help to decrease the frequency of complications
