atrial dissociation is characterized by different types of p waves captured in an electrocardiogram, usually seen in critically ill or post-cardiac transplantation patients. our case demonstrates a 55-year-old man, presenting with chest pain (unstable angina) in the emergency department with transient double-p waves; representing the phenomenon. our case did not have any of the suggested causes...

Background: There is conflicting data about prognostic implication of electrocardiographic (ECG) left ventricular hypertrophy (LVH) in patients with first non- ST-segment elevation myocardial infarction (NSTEMI). We aimed to examine the association of left ventricular hypertrophy (LVH) on admission electrocardiogram with adverse outcomes in patients with NSTEMI. Methods: In the present study, ...

In human several kinds of electrocardiographic findings have been reported in association with pneumothorax such as decreased and/or alternating QRS amplitude (electrical alternans). However, electrocardiographic changes concurrent with pneumothorax have rarely been discussed in veterinary literature. A 3-year-old male crossbreed dog was presented with a history of car accident. Thoracic au...

During the last century the conception of circulatory failure in the course of acute infectious diseases has been subjected to changes in several instances. Circulatory failure of every kind has, of course, a serious influence on the action of the heart itself, and for this reason in infectious diseases it was considered in those early days (1860-95) as heart failure, and the anatomical damage ...

This case report describes several electrocardiographic findings in an 8-years old female Pomeranian dog that was referred with a history of digoxin overdose. Electrocardiographic abnormalities detected in this case could be classified as primary electrocardiographic disturbances, reflecting cardiac chamber enlargement and secondary ECG changes, attributed to digoxin toxicity. ECG manifestatio...

S INCE Huchard used the term tobacco angina in 1899,' there has been much discussion of the relation which it suggests, but few definitive studies of this relation have been published. A review of the literature reveals only two case reports which present objective evidence of myocardial ischemia during angina*1 seizures induced by smoking. 2 It is the purpose of this paper to discuss some of t...
