Nasal spray may offer self treatment option for rapid heartbeat
A novel fast-acting medication delivered through a nasal spray could potentially empower individuals experiencing intermittent rapid heartbeats to treat themselves as soon as symptoms arise, potentially reducing emergency room visits and medical interventions, according to a study published in the Journal of the American Heart Association. The medication is awaiting approval from the U.S. Food and Drug Administration.
During a sporadic episode of the condition called paroxysmal supraventricular tachycardia., patients traditionally employ vagal maneuvers to slow their heart rate. These maneuvers stimulate the vagus nerve, which regulates electrical impulses to the heart's lower chambers. If vagal maneuvers prove ineffective (occurring in about 20-40% of cases), immediate emergency room treatment is typically required, involving intravenous medication to normalize the heart rate.
