Congenital familial nodal rhythm.
IT HAS BEEN KNOWN for years that the more serious cardiac arrhythmias, atrial fibrillatiol, atrial flutter,1 and even ventrieular tachyeardia,2 can exist in persons withouLt demonstrable evidence of heart disease. One of the initial comprehensive reviews of this phenomen-on was that of Orgain, Wolff, aind White1 in 1936, who reported 47 individuals presentinig uncomplicated atrial fibrillation ...
متن کاملCaudocranial conduction in the left auricle in nodal rhythm and in nodal ectopic beats.
As we described elsewhere (Wenger et al., 1950 and 1952) the pattern of aesophageal leads, as registered at various heights above the diaphragm, gives us the chance of drawing conclusions about the conduction in the left auricle. CEsophageal P waves at auricular levels contain well defined intrinsicoid deflections (Brown, 1936; Neuman, 1951; Schwartz, 1947; Wenger, 1947) and the time of their a...
متن کاملDigitalis-induced double atrioventricular nodal rhythm associated with electrical alternans.
An instance of digitalis-induced double atrioventricular nodal rhythm associated with ventricular electrical alternans has been described . To the knowledge of the author, it is the first such combination reported. One atrioventricular nodal pacemaker (group A) produces non-paroxysmal atrioventricular nodal tachycardia and the other pacemaker (group B) produces atrioventricular escape rhythm wi...
متن کاملAn Unusual Case of A-v Nodal Rhythm with Varying A-v Block.
In the human electrocardiogram, A-V block prolongs the P-R interval to values exceeding 02 sec., while nodal rhythm is characterized by P-R intervals ranging from approximately plus 0-12 to minus 0-19 sec. (R-P intervals). The simultaneous occurrence of both A-V block and nodal rhythm may produce P-R intervals within normal range (0d12 to 0-2) ; however, this condition can be recognized by the ...
متن کاملAbsence of junctional rhythm during successful slow-pathway ablation in patients with atrioventricular nodal reentrant tachycardia.
BACKGROUND The presence of junctional rhythm has been considered to be a sensitive marker of successful slow-pathway ablation. However, in rare cases, junctional rhythm was absent despite multiple radiofrequency applications delivered over a large area in the Koch's triangle, and successful ablation was achieved in the absence of a junctional rhythm. METHODS AND RESULTS This study included 35...
