Wellens' syndrome is a pattern of electrocardiographic T-wave changes associated with critical stenosis of proximal left anterior descending artery (LAD). T-waves abnormalities were found in precordial leads, especially in V2-V3 during pain-free periods, and ECG obtained during episodes of pain demonstrates upright T-waves with possible elevated or isoelectric ST segments. ⋯ Although the ECG showed typical T-wave changes in V2-V5 leads, patient's coronary angiography revealed moderate stenosis in proximal LAD, and coronary artery spasm was suggested. Unlike the classic Wellens' syndrome, which needs aggressive coronary intervention, our patient fared well with conservative medical therapy (diltiazem and nitrates) and showed favorable prognosis.

Cortisol dynamics are associated with electrocardiographic abnormalities following the aneurysmal subarachnoid hemorrhage.
Electrocardiographic (ECG) abnormalities are common following subarachnoid hemorrhage (SAH). It probably represents cardiovascular stress after SAH. ⋯ Elevated levels of morning cortisol within the first four days after surgery are associated with the ECG abnormality.

Case ReportsReverse Wenckebach "pseudo-supernormal" conduction or paroxysmal atrioventricular block.
Paroxysmal atrioventricular-block is a poorly-recognized cause of atrioventricular conduction abnormality leading to syncope and can be fatal. Here we report a case of paroxysmal atrioventricular-block presenting as syncope treated effectively with pacemaker implantation and review the current literature on prevalence, known mechanisms and treatment for it. Importantly we provide the diagnostically important differentiating points between vagally mediated block and paroxysmal atrioventricular-block as well as the highlight the vastly varying prognosis between the two.

Case ReportsCoexistence of Cor triatriatum sinistrum and a prominent Eustachian valve mimicking a Cor triatriatum dextrum.
Cor triatriatum is among the rarest of all congenital cardiac abnormalities accounting for 0.1-0.4% of all congenital heart disease. Its coexistence with a very prominent Eustachian valve which mimics a Cor triatriatum dextrum is an exceptionally rare finding in an asymptomatic adult. We report the case of a 44 year old male who presented to our department on observing a pulse rate of 44 beats per minute during a home blood pressure check with his digital sphygmomanometer. ⋯ The diagnosis was made on a two dimensional transthoracic echocardiography. Isolated atrial premature complexes and bradycardia may be a clinical presentation of Cor triatriatum in adult population. Although extremely rare, its coexistence with a prominent Eustachian valve may remain asymptomatic into adult life.

High-dose glucose-insulin-potassium has hemodynamic benefits and can improve cardiac remodeling in acute myocardial infarction treated with primary percutaneous coronary intervention: From a randomized controlled study.
To evaluate the effects of high-dose glucose-insulin-potassium (GIK) solution on hemodynamics and cardiac remodeling in patients with acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI). ⋯ High-dose GIK solution had no adverse effects on the hemodynamics in AMI patients treated with primary PCI. It can improve cardiac function by lowering SVRI. In the 6-month follow-up, it improved cardiac remodeling.
