  Se ha realizado un estudio sobre la incidencia de arritmias cardiacas en el perro, mediante el exámen electrocardiográfico de 2. 200 perros no seleccionados. Se diagnosticaron un total de 1. 651 arritmias cardíacas en un total de 1. 371 perros (62,31 %): 82,01 % (1. 354 casos) fueron ritmos sinusales anormales, 12,53% (207 casos) ritmos ectópicos, y 5,45% (90 casos) bloqueos cardiacos. El 79,86% de los perros (1. 095) presentaron una arritmia aislada el 19,84% (272) dos arritmias asociadas, y el 0,29% (4) tres arriünias' diferentes. En 1. :135 perros de los 2. 200 explorados (51,59 %) se diagnosticaron arritmias vagales, de las que 968 casos fueron arritmia sinusal. Arritmias consideradas como anormales ocurrieron en 236 perros (10,72%), siendo las más frecuentes las siguientes: extrasístoles ventriculares (56,casos), taquicardia paroxística supraventricular (33 casos), bloqueo auriculoventricular de segundo grado (23 casos), bloqueo aurícula ventricular de primer grado (16 casos), y fibrilación auricular (15 casos). * A study on the incidence of cardiac arrhythmias in dogs has been carried out by means of electrocardiographic tracings of 2. 200 dogs at random. A total of 1. 651 cardiac arrhythmias were diagnosed out of a total of 1. 371 dogs (62. 31 %): 88. 02 per cent (1,354 cases) presented abnormal sinus rhythms, 12. 53 per cent (207 cases) ectopic beats, and 5. 45 per cent (90 cases) heart blocks. 79. 86 per cent of the dogs (1. 095) presented isolated arrhythmias, 19. 84 per cent (2 72 cases) two associated arrhythmias, and 0. 29 percent(4) three different arrhythmias. In 1. 135dogs of the 2,200 examined (51. 59%) vagal arrhythmias were diagnosed, of which 968 cases corresponded to a sinus arrhythmia. Arrhythmias considered as abnormal occurred in 236 dogs (10. 72%) the most frequent patbology being thefollounng: ventricular premature beats (56 cases), paroxysmal supra ventricular -tachycardia (33 cases), second degree atrioventricular block (23 cases),first degree atrioventricular block (16 cases), and atrial fibrilation (15 cases).
