WebSep 28, 2024 · The ST segment is the line between the “S” and the “T” on the readout of an EKG. If a person is in good health, the line appears at or close to the baseline level. A depressed or elevated ... WebCommotio cordis (Latin, "agitation or disruption of the heart") is a rare disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart (the precordial region) at a critical instant during the cycle of a heartbeat, 97% fatal if not treated within three minutes. This sudden rise in intracavitary pressure leads to disruption of normal …
WebThe QT interval is a measurement made on an electrocardiogram used to assess some of the electrical properties of the heart.It is calculated as the time from the start of the Q wave to the end of the T wave, and approximates to the time taken from when the cardiac ventricles start to contract to when they finish relaxing. An abnormally long or abnormally … WebThe significance of concordant T wave changes in the leads with a dominant R wave ... When the heart is horizontally inclined, T is also inverted in lead 3. Inverted T waves in other leads may be due to ventricular hypertrophy, myocardial disease, pericarditis and severe hypothyroidism. Flat T waves are seen in myocarditis and hypothyroidism.
The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the T peak –T end interval. [1] In most leads, the T wave is positive. This is due to the repolarization of the membrane. During ventricle contraction (QRS complex), the heart depolarizes. See more In electrocardiography, the T wave represents the repolarization of the ventricles. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. … See more The refractory period of cardiac muscle is distinct from that of skeletal muscle. Nerves that innervate skeletal muscle have an extremely short refractory period after being subjected to an action potential (of the order of 1 ms). This can lead to sustained or See more Both the abnormalities of the ST segment and T wave represents the abnormalities of the ventricular repolarization or secondary to abnormalities in ventricular depolarisation. See more Normally, T waves are upright in all leads, except aVR, aVL, III and V1 leads. Highest amplitude of T wave is found at V2 and V3 leads. The shape of the T wave is usually asymmetrical with a rounded peak. T wave inversions from V2 to V4 leads are frequently found and … See more • Electrocardiography (ECG) • Cardiac action potential • QRS Complex See more WebOther Causes : A slight enlargement in the body part.

WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size.
