Abstract:The value of monitoring the right precordial lead, V4R, to detect peri-operative ischaemic events during coronary artery surgery was studied in 60 patients. Thirty-four patients had only left-sided coronary disease (Group 1). The other 26 patients had both left-sided occlusive coronary artery disease and significant right-sided occlusive lesions on coronary angiography (Group 2). Lead sensitivity was estimated, assuming that all ST segment changes were true positive responses. Sensitivity using a single lead w… Show more
“…Leads V4 and V5 are useful for monitoring anterior ischaemia and leads II, III and AVF view the heart inferiorly. Right ventricular dysfunction is probably viewed best by a V4R lead (4th intercostal space, right midclavicular line) [51,118]; its value in detecting intraoperative ischaemia in patients with right-sided coronary occlusive disease has been demonstrated [23]. Posterior ischaemia is monitored best with an oesophageal lead.…”
