If the arrhythmia is frequent, or causes hemodynamic compromise, in a canine patient, a 2 mg/kg IV bolus of lidocaine should be administered. A clinical response should be seen within minutes. Please note that lidocaine is fast acting and if the patient responds but arrhythmias recur during the anesthetic event, a lidocaine CRI may need to be started (50 mcg/kg/min in a canine patient).


Hypocalcaemia causes neuromuscular and myocardial symptoms, including QT interval prolongation, and cardiac arrhythmias. Prompt detection and calcium 

Se hela listan på academic.oup.com Se hela listan på drugs.com Ventricular Arrhythmias Ventricular arrhythmias can be linked to QT interval prolongation or to direct effects of chemo- and radiotherapy. LV dilatation, dysfunction, fibrosis, and ischemia are all factors that predispose to the development of ventricular arrhythmias. QT duration should be monitored before and during treatment. Apparent ventricular dysfunction can also be due to impaired ability to measure ventricular function during the arrhythmia, or to an underlying cardiomyopathy. Often, only reassessment of ventricular function after ablation of the arrhythmia clarifies the cause. Se hela listan på healthtian.com Se hela listan på vet.cornell.edu The principal cause of sudden death is the occurrence of malignant cardiac arrhythmias, which result in the loss of contraction of the heart with subsequent lack of blood supply to vital organs like the brain. The immediate consequence is loss of conscience, and if the arrhythmia persists for more than 5 minutes, the patient dies.

Signs and symptoms of supraventricular tachycardia may include: A fluttering in your chest. Rapid heartbeat (palpitations) Shortness of breath.

These types of arrhythmias cause your heart to beat too fast, which prevents oxygen-rich blood from circulating to the brain and body and may result in cardiac arrest.
