AI Article Synopsis

  • Dome-and-dart T waves, a rare ECG finding, are typically seen in patients with congenital heart diseases but have not been previously linked to hyperthyroidism.
  • A patient experienced symptoms like tachycardia, palpitations, and chest tightness for several days, leading to a diagnosis of hyperthyroidism.
  • Treatment with methimazole successfully relieved all the patient's symptoms, suggesting a potential connection between dome-and-dart T waves and hyperthyroidism.

Article Abstract

Rationale: Dome-and-dart T waves (or bifid T waves) are a rare phenomenon in the surface electrocardiogram. These wave forms are mainly observed in patients with congenital heart disease such as atrial septal defect and ventricular septal defect. And hyperthyroidism who presented with an electrocardiogram that had dome-and-dart T waves in a precordial lead is never been reported.

Patient Concerns: The patient presented with continuous tachycardia, palpitations, chest tightness, and headache for 4 days, and aggravated for 1 day.

Diagnoses: Hyperthyroidism.

Interventions: Methimazole.

Outcomes: All symptoms were alleviated.

Lessons: Dome-and-dart or bifid T waves have been reported in the conventional 12-lead electrocardiograms in some patients with congenital heart disease. The case illustrated here, to the best of our knowledge, dome-and-dart or bifid T waves may associate with hyperthyroidism patients.

Article Synopsis
  • The text discusses the ECG changes associated with hypokalemia, which are often overlooked compared to those of hyperkalemia.
  • It presents a case study of a patient with severe hypokalemia caused by diarrhea, focusing on the specific ECG changes observed.
  • The case highlights the unique feature of bifid T-waves in hypokalemia and the importance of distinguishing them from changes due to other cardiac conditions, along with the reversal of these changes once potassium levels are restored.

The Lusitano horse is gaining popularity in the equestrian world, and as a result, the significance of applied sports medicine for this breed is growing. As cardiology plays a crucial role in this field, numerous studies have been conducted to establish electrocardiographic reference values in various breeds to ensure a more accurate evaluation. However, studies regarding healthy Lusitano horses are lacking.

Spatiotemporal patterns of early afterdepolarizations underlying abnormal T-wave morphologies in a tissue model of the Purkinje-ventricular system.

PLoS One

January 2023

Henan Engineering Research Center of Health Big Data and Intelligent Computing, School of Public Health, Institutes of Health Central Plains, Xinxiang Medical University, Xinxiang, Henan, P.R. China.

Article Synopsis
  • Sudden cardiac death (SCD) is mainly caused by acute ventricular arrhythmias (VAs), which are influenced by early afterdepolarizations (EADs), particularly in conditions like long QT syndrome (LQTS).
  • A tissue model of the Purkinje-ventricular system was created to study how EADs relate to abnormal T-wave shapes usually seen in LQTS.
  • Findings showed that the dynamics of EADs, including their synchronization and effects on T-wave morphology, can vary significantly based on changes in ion channel activity, influencing the risk of cardiac arrhythmias.

The head-up tilt table test (HUTT) with the upright phase is used to help determine an imbalance of the sympathetic nervous system that is related to abnormal electrocardiographic repolarization in children with vasovagal syncope (VVS) and also in patients with the long QT syndrome (LQTS). The study attempted to evaluate T wave morphology and QT and TpTe (Tpeak-Tend) intervals recorded in ECG during the HUTT for a more accurate diagnosis of children with VVS. The group investigated 70 children with a negative HUTT result: 40 patients with VVS and 30 healthy volunteers without syncope.

We briefly describe a case of a 31-year-old man with persistent hyperthyroidism, despite medical treatment with high dose methimazole. Twelve-lead 24-hour Holter monitoring showed bifid (or dome-and-dart) T waves and echocardiography revealed mild left ventricle dilatation. Hyperthyroidism was eventually treated with total thyroidectomy, and thereafter, T waves became normal and the left ventricle returned to normal dimensions.
