On-Demand Therapy for PSVT
Millions of individuals experience episodes of rapid heart rhythm known as paroxysmal supraventricular tachycardia (PSVT). Instances of PSVT occur suddenly, with patients often experiencing racing heartbeats of 200 beats per minute or more. The uncertain nature of when an episode may occur, along with the accompanying symptoms of the palpitations, equates to a stressful and even debilitating state for those with the condition. A noteworthy new therapy has obtained regulatory approval, bringing the first self-administered treatment option for PSVT to patients.
PSVT is a subset of supraventricular tachycardias that originate in the atria or atrioventricular (AV) node and start and stop abruptly, and may recur over several minutes or days. PSVT can occur in both adult and pediatric patients. In addition to an accelerated heart rate, patients may experience dyspnea, severe palpitations, chest discomfort, weakness, nausea, dizziness, or syncope. In addition, anxiety and concerns about the unpredictable onset of symptoms may be factors that patients with PSVT contend with that interfere with and impede daily activities. While PSVT is usually not life-threatening, frequent or prolonged episodes can impair quality of life and, in rare cases, contribute to cardiomyopathy if left untreated.
Diagnosis of PSVT is typically confirmed by a 12-lead electrocardiogram captured during an episode of arrhythmia and after cardioversion. Initial acute management in stable patients typically includes vagal maneuvers to enhance vagal tone and interrupt the reentrant circuit. Vagal maneuvers may include having the patient cough forcefully or holding the nostrils closed while attempting to expel air through them. Another method used is carotid sinus massage, with gentle pressure applied to the neck over where the carotid artery splits into two branches.
When vagal maneuvers fail or are inappropriate, anti-arrhythmic medications are used for treatment. Adenosine is frequently used in clinical settings for rapid termination because of its short half-life and its effectiveness in transiently blocking AV nodal conduction. Intravenous non-dihydropyridine calcium channel blockers such as verapamil or diltiazem may also be considered subsequently. In recurrent or refractory cases, catheter ablation offers a definitive treatment, often with remarkably high success rates.
The newest treatment option to become available is the recently FDA-approved nasal spray Cardamyst (etripamil). It is indicated for the conversion of acute symptomatic PSVT episodes to normal sinus rhythm in adults outside of healthcare settings. This approval represents the first self-administered pharmacologic option specifically indicated for PSVT in decades and offers patients autonomy in managing acute episodes. Etripamil is a short-acting, calcium channel inhibitor delivered intranasally. By rapidly inhibiting calcium influx in the AV nodal cells, it slows AV nodal conduction and disrupts the reentrant circuit sustaining PSVT, aiding return to sinus rhythm. The intranasal route enables quick absorption and rapid onset of action, making it suitable for on-demand use. In clinical trials, patients taking etripamil were twice as likely to convert symptomatic PSVT to sinus rhythm and did so three times faster than patients taking a placebo.
The advent of intranasal etripamil marks a paradigm shift in PSVT management by empowering patients with a rapid, self-administered treatment option. Positive outcomes may include reduced reliance on emergency care and improved patient quality of life, enabling swift termination of episodes outside clinical environments. Ongoing post-marketing surveillance and further studies will continue to refine its role in patient care.
