A compensatory pause is seen after the second VPC. The basic sinus cycle length is near 600 milliseconds corresponding to a rate of around 100 per minute. Sweep speed of the monitor is shown as 25 millimeters per seconds and the standardization at 1 millivolt to a centimeter. Sinus beats also show T wave inversion, possibly due to underlying primary T wave change due to ischemia \/ infarction, which has caused the myocardial irritability in the form of VPC couplet. Though VPC couplets themselves are harmless, they could be a forerunner of ventricular tachycardia, which needs to be anticipated and treated if if occurs.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>VPC couplet &#8211; ECG strip VPC Couplet Monitor screenshot showing ventricular premature complexes in a couplet form (VPC couplet), with no preceding sinus beat in between.
