Postoperative real-time electrocardiography monitoring detects myocardial ischemia: a case report

PurposeThis case report outlines the utility and challenges of remote continuous postoperative electrocardiography ECG) monitoring, which is routed through a secure smartphone to provide real-time detection and management of myocardial ischemia.Clinical featuresA 42-yr-old male with previous myocardial infarction and angioplasty underwent a radical prostatectomy. At three hours and 45 min postoperatively, remote real-time ECG monitoring was initiated upon the patient’s arrival on a regular surgical ward. Monitor alerts were routed to a study clinician’s smartphone. About six hours postoperatively, alarms were received and horizontal ST segment depressions were observed. A 12-lead ECG validated the ST segment changes, prompting initiation of a metoprolol iv and a red blood cell transfusion. Approximately seven hours and 30 min postoperatively, the ST segments normalized. The patient was discharged on postoperative day 3 and followed for four years without any sequelae.ConclusionThis case report illustrates the use of remote ECG monitoring and clinician response in real time with the use of a smartphone. With each alert, a small ECG strip is transmitted to the smartphone for viewing. In our view, this technology and management system provides a possible means to interrupt myocardial ischemic cascades in real time and prevent postoperative myocardial infarction.RésuméObjectifCette présentation de cas décrit l’utilité et les défis d’un monitorage électrocardiographique (ECG) postopératoire continu à distance, dont le signal est acheminé via un téléphone intelligent sécurisé pour permettre la détection et la prise en charge en temps réel de l’ischémie myocardique.Éléments cliniquesUn homme de 42 ans présentant des antécédents d’infarctus du myocarde et d’angioplastie a subi une prostatectomie radicale. Trois heures et 45 minutes après l’opération, un monitorage ECG en temps réel a été lancé à distance, soit à l’arrivée du patient dans un service régulier de chirurgie. Les alertes du moniteur ont été acheminées vers le téléphone intelligent d’un clinicien de l’étude. Après environ six heures postopératoires, des signaux ont été reçus et des sous-décalages horizontaux du segment ST observés. Un ECG à 12 dérivations a permis de valider les changements au segment ST, incitant l’amorce d’une iv de métoprolol et une transfusion d’érythrocytes. Approximativement sept heures et 30 minutes après l’opération, les segments ST se sont normalisés. Le patient a reçu son congé au 3ème jour postopératoire, puis il a été suivi pendant quatre ans sans séquelles.ConclusionCette présentation de cas illustre l’utilisation d’un monitorage ECG à distance et la réponse du clinicien en temps réel à l’aide de son téléphone intelligent. Lors de chaque alerte, une petite bande de rythme ECG est transmise au téléphone intelligent pour être visionnée. Selon nous, cette technologie et ce système de gestion offrent une possibilité d’interrompre les cascades d’ischémie myocardique en temps réel et de prévenir l’infarctus du myocarde postopératoire.
