DISSOCIATION WITH INTERFERENCE, RECIPROCAL RHYTHM, AND CORONARY SINUS RHYTHM

Dissociation with interference, reciprocal rhythm, and coronary sinus rhythm.

Reversed reciprocal rhythm.

An example of reversed reciprocal rhythm is presented with associated 2:I heart block and other abnormalities of conduction. The electrocardiograms have been analysed and compared with an earlier electrocardiogram in which sinus rhythm was present. Despite dramatic electrocardiographic abnormalities, evidence is offered which suggests that there may have been only a small alteration in activity...

Artificial Pacemaking and Sinus Rhythm.

The patients reported form part of a larger series of 60 patients with Stokes-Adams disease treated with artificial pacemakers, which is being reported in full elsewhere. The series contained 32 men between the ages of 39 and 81, and 28 women between 27 and 76. There was a bias towards the older age-groups with 53 per cent of the men and 62 per cent of the women being over 65 years. No patients...

Coronary sinus rhythm in anomalous systemic venous connection.

YSTEMIC venous anomalies, such as persistent left superior vena cava and absent inferior vena cava, are not so rare in various congenital heart diseases.1) Preoperative identification of these anomalous systemic venous connections is clinically important, because their presence necessitates modified technique for venous cannulation of cardiopulmonary bypass. In cases of persistent left superior...

Left Superior Pulmonary Vein Rhythm Masquerading as Sinus Rhythm

A 55 year old male with a history of frequent symptomatic episodes of paroxysmal atrial fibrillation (AF) for four years was referred to us for catheter ablation. He had earlier tried flecainide and sotalol. However he was unresponsive to both of them. The echocardiogram was normal. Figure 1, left panel demonstrates his baseline electrocardiogram. The relatively slow rate and regularity of this...
