The v20 measures 1 changed from using response scores of 0-4 to use 1-5 item IDs amended with an r and 2 added new items item IDs start with 7000. ST depression can be either upsloping downsloping or horizontal.

The ECG revealed sinus rhythm narrow QRS complex ST-segmentelevation in lead V1 and V2 with a slight elevation in leads III and aVF and 1-mm ST-segmentdepression in leads I and aVL.
T depression in v1 v2. So St depression in v2 and v3. ST elevation in V1 V2 V3 V4 ST depression in II III aVF Inferior. St dePression t inVersion with isolated T-wave inversion without ST-segment depression in precordial leads V 1 V 2 and V 3.
Left ventricular hypertrophy may be as-sociated with symmetric T-wave inver-sion without ST-segment depression or with a horizontally depressed ST seg-6. There were no differences in time from symptom onset to hospital admission or in the culprit lesion among the three groups. ST elevation in II III aVF ST depression in V1 V2 V3 or I aVL Lateral.
Dominant R wave RS ratio 1 in V2. When the ecg is recorded how come in some of the examples above leads v4 5 and 6 are crossed out and replaced by leads v7 8 and 9. Swap leads v4 5 and 6 and place them on the posterior aspect of the thorax as per diagram.
02 mV in men 40 years 025 mV in men ST depression helps confirm the diagnosis. For depression v20 pediatric and parent proxy measures replaced v10v11. Tall wide R waves and ST depression in V1 V2.
Disproportionate ST segment depression ST elevation in inferior lead is 2 mm while ST depression in v1v2 v3 is 3 mm Persistence of ST depression even after thrombolysis or PCI to IRA. Sympathetic stimulation and hypokalemia causes non specific ST segment changes. Worsening with thrombolysis would suggest ST depression in V1V2 and v3 is indeed an episode of true NSTEMI of LAD where thrombolysis is contraindicated.
On contrast some examples have v1 2 and 3 cross out and are replaced by v7 8 and 9. ST elevation in I aVL V5 V6 ST depression in II II aVF Septal wall. In patients presenting with ischaemic symptoms horizontal ST depression in the anteroseptal leads V1-3 should raise the suspicion of posterior MI.
Upsloping ST depression in the precordial leads with prominent De Winter T waves is highly specific for occlusion of the LAD. These depressions are horizontal or downsloping. T-wave inversions are also present in V1 V2 V3 II III avF.
Posterior MI is suggested by the following changes in V1-3. This is an example illustrating the need to analyze ST depressions ST elevations T-wave inversion. These are consistent with and more nearly suggestive of T-wave inversion of ischemiainfarction.
Digoxin digitalis digitoxin causes downsloping ST depression with a characteristic sagging appearance. Tall broad R waves 30ms Upright T waves. Sympathetic stimulation and hypokalemia.
Surprisingly no pathological Q waves were evidenced after more than 3 hours of chest pain. The degree of ST-segment elevation in leads II III aVF V5 or V6 the degree of ST-segment depression in leads V1 to V4 and the sum of ST-segment deviation in these leads were lowest in group A and highest in group C. Heart failure may cause ST segment depressions in left sided leads V5 V6 I and aVL.
ST elevation in I aVL V1 V2 Posterior. While true that RV strain will not always be seen in both of these lead areas the fact that there is no sign at all of inferior ST-T wave depression within the PURPLE rectangles and the somewhat less usual pattern of ST-T wave depression in the anterior leads within RED rectangles showing maximal ST-T wave depression in lead V2 despite only modest R wave amplitude in this lead to me suggested that the anterior ST-T wave depression. MV in all leads other than leads V2-V3 For leads V2-V3 the following cut points apply.
The calibrations between v10 v11 and v20 are identical. Horizontal or downsloping ST depression 05 mm at the J-point in 2 contiguous leads indicates myocardial ischaemia according to the 2007 Task Force Criteria. R-wave 40 ms in V1-V2 and RS 1 with a concordant positive T-wave in the absence of a conduction defect ST depression 26 ST-segment depression of 1 mm or more 60-80 ms after the J point.
