Use of a smartphone electrocardiogram to diagnose arrhythmias during exercise in athletes: a case series.

Background: While athletes are generally very fit, intense exercise can increase the risk of atrial fibrillation. Moreover, other arrhythmias such as atrial flutter or supraventricular tachycardia can cause distressing, exercise-related symptoms. Given symptoms are infrequent and may occur during intense exertion, traditional monitoring devices are often impractical to use during exercise.

Life after COVID-19: The importance of a safe return to physical activity.

The Australasian College of Sport and Exercise Physicians has developed a guideline for primary care practitioners to assist with safe return of patients to physical activity after COVID-19.

Does moxonidine reduce Achilles tendon or musculoskeletal pain in women with polycystic ovarian syndrome? A secondary analysis of a randomised controlled trial.

Background: Sympathetic activity and insulin resistance have recently been linked with chronic tendon and musculoskeletal pain. Polycystic ovarian syndrome is linked with insulin resistance and increased sympathetic drive and was therefore an appropriate condition to study the effects of modulating sympathetic activity on Achilles tendon and musculoskeletal symptoms.

Methods: A secondary analysis of a double-blinded, randomised controlled trial on women with polycystic ovarian syndrome was conducted.

The sympathetic nervous system and tendinopathy: a systematic review.

Background: Tendinopathy is a clinical diagnosis of localised tendon pain often confirmed by imaging findings. The pathophysiological cause of the pain is unknown and the sympathetic nervous system (SNS) may be implicated.

Objective: To review what is known regarding the role of the SNS in human tendinopathy.
