Pacemaker electrode implantation in patients with persistent left superior vena cava.

Four out of 661 consecutive patients with permanent endocardial VVI pacing had the pacing lead introduced through a persistent left superior vena cava. It was difficult to introduce the lead from the right atrium into the right ventricle because the tip of the lead tended to be deflected away from the tricuspid orifice. This difficulty was overcome by shaping the lead into a pigtail with 3-4 cm wide loop. This avoided the risk of entering a branch of the coronary sinus in order to reach the right atrium. This technique made it easier to position the lead in the right ventricular apex. There were no complications in these four patients during a mean follow up of three years.

[The case of the "runaway pacemaker"].

A case of a runaway pacemaker is described. Malfunctioning pacemaker produced stimuli with changeable amplitude and fast rate. It was a reason of intermittent capture, producing a variable ventricular rate; periods of life-threatening pacemaker-induced ventricular tachycardia or uneffective stimulation with slow ventricular escape rhythm. Although runaway pacemaker is a rare complication in modern pacemakers, but it still exists. It usually occurs as an emergency situation requiring immediate correction.

Acute myocardial infarction--prehospital and posthospital phases.

The prognosis of acute myocardial infarction depends to a large extent on quick access to medical facilities, preferably in a hospital. Total delay in hospitalization (THD) consists of patient's delay (PD--time from the onset of the attack to the call for a doctor), doctor's delay (DD--time from the call for a doctor to his arrival), and hospitalization delay (HD--time from the doctor's arrival to the admission in a hospital). In a group of 507 cases of acute myocardial infarction the median THD was 215 min., PD--95 min., DD--20 min., HD--35 min. Better interpretation of symptoms both by the patient and the doctor seems to be one of the most effective means of shortening the total hospitalization delay. The final outcome of infarction in terms of the patient's return to normal life depends on proper rehabilitation and treatment in the posthospital phase.
