Although relatively rare, oral antiarrhythmic medications may be proarrhythmic in some dogs; consequently, appropriate monitoring and follow-up is recommended. [2] [11] The ideal therapy for Boxer cardiomyopathy would be implantation of an implantable cardioverter-defibrillator (ICD). This has been attempted in a limited number of dogs. [12]
This person was eventually diagnosed with tachycardia-induced cardiomyopathy. [7] There are no specific diagnostic criteria for TIC, and it can be difficult to diagnose for a number of reasons. First, in patients presenting with both tachycardia and cardiomyopathy, it can be difficult to distinguish which is the causative agent. [5]
Complications of reflex syncope include injury due to a fall. [1] Reflex syncope is divided into three types: vasovagal, situational, and carotid sinus. [2] Vasovagal syncope is typically triggered by seeing blood, pain, emotional stress, or prolonged standing. [11] Situational syncope is often triggered by urination, swallowing, or coughing. [2]

The management of tachycardia depends on its type (wide complex versus narrow complex), whether or not the person is stable or unstable, and whether the instability is due to the tachycardia. [10] Unstable means that either important organ functions are affected or cardiac arrest is about to occur. [ 10 ]
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...
