…to patients with symptoms. Current guidance supports revascularisation for significant left main stenosis irrespective of symptomatic status or the documented ischaemic burden. In chronic coronary…

…first half of the P wave is therefore a reflection of right atrial activation and the second half is a reflection of left atrial activation…

…hypertension with or without left ventricular hypertrophy. Among patients with NSTE ACS undergoing angiography, approximately 10% have no critical epicardial stenosis. In some of these…

…the left ventricle is many times larger than the vector generated by the right ventricle, the QRS complex is actually a reflection of left ventricular…

…the inferior wall of the left ventricle. This type of bradycardia is due to diminished automaticity (pacemaker function) in the sinoatrial node or conduction defects…

…or supranormal ejection fraction , despite manifest heart failure and severe symptoms. These individuals exhibit pronounced hypertrophy, resulting in a reduction of ventricular volume and subsequently…

…mass. Tamponade occurs when intrapericardial pressure equals or exceeds right atrial pressure. The haemodynamic consequences are progressive impairment of right and left sided filling, reduced…

…negligible, and doses do not require reduction in patients with renal disease; neither amiodarone nor desethylamiodarone is dialyzable. The volume of distribution is large, averaging…

…left ventricle is usually considerably larger than the right ventricle, the QRS complex is actually a reflection of the electrical potentials generated by the left…

…generally results from abrupt reduction in coronary blood flow caused by thrombotic occlusion of a previously atherosclerotic artery. Plaque erosion or rupture exposes thrombogenic material…
