Relationship between door-to-balloon time and clinical experience level of emergency department physicians.

Background: This study aimed to investigate the relationship between the experience level of physicians initially making the clinical diagnosis of ST-segment elevation myocardial infarction in the emergency department and door-to-balloon time (DBT).

Material And Methods: The study group comprised 522 patients with ST-elevation myocardial infarction who were immediately treated in the catheter laboratory. Information about DBT, the experience level of the physicians who initially clinically diagnosed the patients and clinical benefit parameters were collected.

The effect of low iron storage without Anaemia on electrocardiography.

Background: Low iron storage is a common health problem around the world. Although the association of low iron storage with cardiovascular events and various electrocardiographic parameters has been investigated, its association with fragmented QRS (fQRS), T-T (Tp-e) interval, Tp-e/QT and Tp-e/QTc ratios, which are important criteria for repolarization, has not been studied in adults.

Methods: A total of 201 female patients in the 18-50 age group with no history of chronic and cardiac disease or anaemia were included in the study.

Comparison of the refractive measurements with hand-held autorefractometer, table-mounted autorefractometer and cycloplegic retinoscopy in children.

Purpose: To evaluate the performance of the hand-held and table-top autorefractokeratometer in measuring refractive errors by comparing them with cycloplegic retinoscopy.

Methods: Included in the study were 112 eyes of 112 pediatric patients whose mean age was 6.78 ± 2.
