What is the J point? Point at which QRS ends and ST segment begins. What does a normal T wave look like? 1. upright in all leads except aVR & VI 2. asymmetric (leads toward right) 3. goes same direction as R wave in that same lead ...
J Wave. Osborn waves or “J” waves are seen mostly during hypothermia. This wave presents a small deflection at the junction, “J,” of the QRS complex and the ST segment. Epsilon Wave. Should you happen upon one, the Epsilon wave is not common. If you notice a regularly occurring, ...
J point = point at which the QRS finishes and the ST segment begins used to measure ST elevation or depression J wave – can appear as a small wave after the QRS pathogenic – hypothermia and hypocalcemia (low Ca) ST segment (80-120msec) = end of QRS ...
• J point = point at which the QRS finishes and the ST segment begins –used to measure ST elevation or depression • J wave – can appear as a small wave after the QRS –pathogenic – hypothermia and hypocalcemia (low Ca)

J Point - end of QRS + begin of T, ↑ or ↓ of ST. Depression = ischemia; elevation = injury. 1mm is nml. T waves – ventric repole, last part of ventric systole. R on T phenomenon – leads to vfib; ♥ not pumping properly. Something other than p-maker is acting, leading...
Hyperthermia or “heat stroke” is characterized by uncontrolled elevation in body temperature that exceeds the body's ability to lose heat. Thus, in contrast to fever, the “set-point” of the hypothalamic thermoregulatory center is unchanged. It is often characterized by core body temperatures of...
