Introduction Patients presenting with tachycardia most often complain of palpitation and dizziness, but can also report episodes of chest pain due to increased myocardial oxygen demand. The aim of this case article was to emphasize the importance of differential diagnosis between different types of supraventricular (SVT) or ventricular tachycardia (VT) according to ECG findings, and highlight the treatment algorithm for wide QRS-complex tachycardia. Case Outline We present a 34-years old female patient which was admitted to our hospital due to palpitations and chest pain that occurred at rest about two hours before hospital admission. Cardiac auscultation showed the presence of irregular heartbeats with tachycardia, whereas arterial blood pressure was 100/60 mmHg. Initial ECG recording demonstrated wide complex tachycardia (WCT) with irregular heart rate of approximately 180 beats per minute with right bundle branch block-like morphology of QRS complexes. After administration of intravenous amiodarone, patient was converted to sinus rhythm, with short PR interval (< 120 ms) and narrow QRS complexes (< 120 ms) with visible delta waves, indicating the presence of Wolff–Parkinson–White syndrome type A as the underlying cause of atrial fibrillation with right bundle branch block-like morphology of QRS complexes. Conclusion The ability to differentiate between VT and SVT with a wide QRS complex due to aberrant intraventricular conduction or preexcitation is critical because the treatment of each is different, and inadequate therapy may potentially have lethal consequences. © 2018, Serbia Medical Society.

Introduction Congenital anomalies of the aortic arch, although numerous and heterogeneous, occur in less than 1% of individuals at autopsies. Left aortic arch with an aberrant right subclavian artery, also called arteria lusoria dextra, is the most common anomaly of the aortic arch, occurring in 0.5-2.5% of individuals. Case Outline We report the case of a 48-year-old man suffering from acute inferoposterior-wall ST elevation myocardial infarction successfully treated by primary percutaneous coronary intervention. Ten years ago, the patient had undergone coronary artery bypass graft surgery with the implantation of two arterial grafts - left and right internal mammary arteries on both left anterior descending and right coronary artery. After several attempts to canulate truncus brachiocephalicus, angiogram revealed the left aortic arch with the aberrant right subclavian artery. To our knowledge, this is the first described case of primary percutaneous coronary intervention via the aberrant right subclavian artery and right internal mammary artery graft with stent implantation in the infarct related lesion of the distal segment of right coronary artery. Subsequent 64-multidetector computed tomography confirmed the angiographic findings. Conclusion Early recognition of congenital anomalies of the aortic arch and its great vessels, even before coronary artery bypass graft surgery, could be crucial for the urgent and successful treatment of patients with life-threatening conditions, such as ST segment elevation myocardial infarction.

All original articles and meta-analysis use the single cut-off value to distinguish high-risk hyperglycemic from other acute myocardial infarction (AMI) patients. The mortality rate is 3.9 times higher in non-diabetic AMI patients with admission glycemia ≥6.1 mmol compared to normoglycemic non-diabetic AMI patients. On the other hand, admission hypoglycemia in AMI is an important predictor of mortality. Because both admission hypo- and hyperglycemia correspond to higher in-hospital mortality, this graph is recognized as “J or U shaped curve”. The review suggests two cut-off values for admission glycemia for risk assessment in AMI instead of single one because hypoglycemia as well as hyperglycemia represents a high-risk factor. © 2020 Primary Care Diabetes Europe
