noninvasive oscillometric blood pressure monitoring were instituted. Ventricular bigeminy was noted, with a right bundle branch block morphology and a ventricular rate of 80 beats/min ( Figure 1 ) . Noninvasive blood pressure was also normal, with an average

An 8-year-old spayed female Boxer was examined because of refractory ventricular arrhythmias that had not resolved after treatment at another referral institution. Initial physical examination revealed tachycardia (heart rate, 250 beats/min), weak

Arrhythmogenic right ventricular cardiomyopathy is a form of cardiomyopathy characterized by fibrofatty infiltration of the right ventricle and, in some situations, the interventricular septum and left ventricular free wall in Boxers. 1

Hydrocephalus is a condition characterized by the accumulation of CSF within the ventricular system of the brain. A positive correlation between hydrocephalus and short stature or slow growth velocity has been reported for humans. 1 Therefore, it

/s. The TDI profiles were recorded as 1 positive wave (ventricular systole) and 2 negative (early and late) diastolic waves, which were modulated by the β-adrenergic receptor agonist and antagonist. Echocardiographic measurements of the myocardial velocity

Transvenous cardiac pacing is a common procedure performed in humans and other animals with clinical bradyarrhythmias, and the RVA is the traditional site of ventricular lead implantation because of ease of placement. As early as 1925, Wiggers 1
