Dr. Davis emphasizes that valve damage is not only caused by poor dietary habits, explaining, “Diet is often talked about in connection to heart disease, but valve damage has different causes.
It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia. It is more common in women than men (approximately 75% of cases occur in females). The main symptom is palpitations.
Often, symptoms mimic those of congestive heart failure (esp. activity intolerance and dyspnea), but treatment of each is different. Beta blockers are used in both cases, but treatment with diuretics, a mainstay of CHF treatment, will exacerbate symptoms in hypertrophic obstructive cardiomyopathy by decreasing ventricular preload volume and ...
If these maneuvers fail, using intravenous adenosine [4] causes complete electrical blockade at the AV node and interrupts the reentrant electrical circuit. Long-term management includes beta blocker therapy and radiofrequency ablation of the accessory pathway.
Valve repair is where the valve that is causing heart failure is modified by removing excess valve tissues that cause them to close too tightly. In some cases, annuloplasty is required to replace the ring around the valves. If the repair of the valve is not possible, it is replaced by an artificial heart valve. The final step is heart replacement.

[3] Sinus tachycardia is a normal response to physical exercise or other stress, when the heart rate increases to meet the body's higher demand for energy and oxygen, but sinus tachycardia can ...
