However, a large defect can result in heart failure or in pulmonary hypertension leading to a right-to-left shunt.

Boxer cardiomyopathy (also known as "Boxer arrhythmogenic right ventricular cardiomyopathy") is a disease of the myocardium primarily affecting Boxer dogs.It is characterized by the development of ventricular tachyarrhythmias, resulting in syncope and sudden cardiac death.
The research showed that dog parents prone to negative affectivity, which involves feelings of anxiety, insecurity, and sensitivity, interestingly have higher heart rate variability.
Although presentations vary, individuals with right ventricular hypertrophy can experience symptoms that are associated with pulmonary hypertension, heart failure and/or a reduced cardiac output. These include: [1] [2] Difficulty breathing on exertion; Chest pain on exertion; Fainting on exertion; General fatigue/lethargy; Dizziness
