Therapeutic Hypothermia‐Induced Electrocardiographic Changes and Relations to In‐hospital Mortality

BackgroundTherapeutic hypothermia improves survival for selected patients who remain comatose after cardiac arrest. Hypothermia triggers changes in electrocardiographic (ECG) parameters; however, the association of these changes to in‐hospital mortality remains unclear. HypothesisQT interval changes induced by therapeutic hypothermia are not associated with in‐hospital mortality. MethodsWe retrospectively compared precooling ECG parameters to ECG parameters during hypothermia on all consecutive patients with available information who received hypothermia at our academic medical center between December 2006 and July 2012 (N = 101; 24% women). Paired 2‐sample t test was used to compare precooling vs cooling ECG parameters. In‐hospital mortality related to ECG parameter changes was compared using the Pearson χ2 test. ResultsTherapeutic hypothermia resulted in increases in PR and QTc intervals and decreases in heart rate and QRS intervals (P for all

CONCLUSIONS:  OW was observed in all hypothermic patients with VF/VT. The occurrence of ventricular arrhythmias is highly unlikely in the absence of OW on the electrocardiogram. Although the presence of OW might be used to predict these fatal arrhythmias in hypothermic patients, there was no association between the presence of OW and in-hospital mortality.

cı S Abstract An Osborn wave may be observed on an electrocardiogram (ECG) as a late delta wave at the end of the QRS complex in cases of hypothermia. An 18-year-old male known to be a synthetic cannabinoid user was found unconscious and hypothermic. The patient's body temperature was 33ºC, and an Osborn wave and atrial fibrillation were detected in ECG readings. Following the application of heating and supportive therapy, consciousness returned and the ECG findings improved. Rewarming and supportive treatment can be life-saving in a hypothermic patient when initiated as soon as possible. PMID: 31219440...

CONCLUSION: Our study has shown that fasting times in our population is far longer than recommended and fasting prolonged>15 hours is related to a transiently increased cardiac stress and mild hypothermia. PMID: 30892395 [PubMed - in process]

A man with a history of drug abuse was found down at home and was asystolic. Following restoration of sinus rhythm, a hypothermia protocol brought his temperature to 32.5 °C (90.5°F), and large Osborn waves appeared on his electrocardiogram. With rewarming the electrocardiographic signs of hypothermia diminished. Due to hypoxic brain injury during the arrest, the patient remained unresponsive and died on the 4th hospital day.

ABSTRACT: Objective: To examine the medical assessment and triage of pediatric patients with anorexia nervosa (AN) initially seen in primary care. Methods: A retrospective cohort study was conducted for all pediatric patients with AN who had eating/weight concerns and initially identified symptoms in primary care in a single health care system between January 1, 2010, and December 31, 2016. Information on presenting concern, medical assessment/laboratory tests, clinical diagnoses, treatment recommendations, and referrals were abstracted from the medical record. Results: Forty-one (mean age = 13.7 years; SD = 2.2)...

The Neonatal Resuscitation Program, initially an expertise- and consensus-based approach, has evolved into an evidence-based algorithm. Ventilation remains the key component of successful resuscitation of neonates. Recent changes in recommendations include management of cord clamping, multiple methods to prevent hypothermia, rescinding of mandatory intubation and suction of the nonvigorous meconium-stained infant, electrocardiographic monitoring, and establishing an airway for ventilation before initiation of chest compressions. Emerging science, including issues such as cord milking, oxygen targeting, and laryngeal mask u...

Authors: Miyoshi M, Kondo H, Shinohara T, Yufu K, Nakagawa M, Takahashi N Abstract We herein report a case of a 53-year-old man who survived cardiac arrest due to ventricular fibrillation (VF). When admitted to the hospital, his 12-lead electrocardiogram did not show Brugada-like ST elevation, early repolarization or delta-wave, in any leads. During the treatment of hypothermia, the manifestation of delta-wave was documented, which disappeared after the cessation of this treatment. A cardiac evaluation showed no structural heart disease, and electrophysiology studies did not demonstrate conduction via accessary pat...
