About 30% of patients with Heart Failure (HF) have wide QRS complexes. In left bundle branch block (LBBB), the electromechanical activation sequence in the Left Ventricle (LV) is asynchronous with deterioration of pump function, higher frequency of hospitalizations and mortality.

[Restoration of effective artificial cardiac pacing by isoproterenol].
Harefuah, 1992Since the pacing threshold of artificial pacemakers sometimes increases and causes ineffective pacing, emergency restoration of cardiac pacing may occasionally be required. In such situations sympathomimetic agents, such as isoproterenol, increase excitability and lower threshold.

Transvenous placement of a right ventricular pacemaker lead through the artificial tricuspid valve is a known contraindication, and in this situation, epicardial pacemaker implantation is the procedure of choice. However, permanent pacemaker implantation is a subject for debate when the use of the epicardial route is impossible.

A case of haemodynamic decompensation is reported in a patient with a sick-sinus syndrome on a demand cardiac pacemaker, under-going surgery under general anaesthesia. While systemic arterial blood pressure showed adequate stability under the patient's own sinus drive, it consistently fell by 15 to 20 p. cent when artificial pacing was established. The

Twenty-four-hour recordings of electrocardiogram (ECG) were obtained from 1528 subjects. Sick sinus syndrome (SSS) was observed in 34 and advanced or complete AV block (CAVB) in 13 subjects. During the period studied 21 patients had died, who showed complicated ventricular premature contractions in 9 (multiform 6, short run 2, repetitive 2).
