We report a case of true syncope with documented vasovagal syncope which occurred at the time of an alarm due to missile attack. This case shows a severe vasovagal reaction to emotional stress and fear.

The vasovagal response (neurocardiogenic response) involves an abnormal interplay of bradycardia and paradoxical vasodilation. This intense vagal stimulation can result in syncope, which may have dramatic consequences, especially in elderly patients. Such an event was triggered during a missile alarm in an 80-year-old man. To the best of our knowledge, no similar case has been previously reported [1,2]. A sinus pause is a temporary cessation of electrical impulses from the sinus node, resulting in a brief but complete halt of heart contraction. The excessive vagal input diminishes sinus node automaticity, potentially causing pauses that vary in duration from seconds to even longer periods, depending on individual susceptibility and the length and intensity of the vagal response.

Although typically transient, sinus pauses may also result in significant symptoms like lightheadedness or syncope. In severe cases, they can compromise cerebral perfusion, necessitating immediate intervention. Recognizing the risk of sinus pause in susceptible patients is essential for preventing potential complications, particularly during procedures that may provoke a strong vasovagal reaction.

Standup paddleboard surfing (SUP) is a sports activity in which a person stands upright on a surfboard and propels the board using a single paddle. It is an emerging recreational activity that is attracting public attention and gaining popularity because it promotes fitness, strength, and improved balance. In this review, we discuss the outcomes after severe cardiac events in SUP surfers. We report on six fit individuals (five males and one female, age range 41–69 years) who experienced sudden cardiac arrest (n=3) or acute myocardial infarction occurring during SUP. Cardiopulmonary resuscitation was initiated in three patients on presentation due to ventricular fibrillation. In four patients the culprit coronary artery was the left anterior descending artery treated by percutaneous coronary intervention. All patients were discharged alive. A review of the literature showed a paucity of scientific evidence to substantiate the proposed health benefits of SUP surfing. Our cluster of acute cardiac events occurring during this activity calls for heightened public awareness to better understand the physical demand required to practice SUP. There is a need for more data regarding the cardiovascular clinical aspects of this water activity, and the risks it entails.
