Sydäninfarktissa EKG:hen tulee muutoksia, joista voidaan päätellä, mitä sydämen osaa lihaskuolio on uhkaamassa. Samalla selviää kuinka laaja sydänlihasvaurio on. Kun potilas on rintakipuinen, lääkäri voi päättää EKG:n perusteella, onko liuotushoito aiheellista.

Limb leads: I, II, III, IV, V, and VI Lead IV also called AVR Lead V also called AVL It follows that the ECG waves in lead aVF, at any given instance, is the average of the ECG deflection in leads II and III. Hence, leads aVR/–aVR, aVL and aVF can be calculated by using leads I, II and IIII and therefore these leads (aVF, aVR/–aVR, aVL) do not offer any new information, but instead new angles to view the same information. Nonspecific: The t wave is more commonly upright in those leads; when it is upside down (a negative deflection), it is inverted.

Step 3 Axis Next we need to determine the AXIS of the EKG tracing. To do this we need to understand the basic 6 leads and their geometry. The EKG waveform comes from a measurement of surface voltages between 2 leads.

Pericarditis, or inflammation of the pericardium, has typical ECG findings. These findings occur in progressive stages, all of which are seen in about 50% of cases of pericarditis.

Example #2: Old inferior Q-wave MI; note largest Q in lead III, next largest in aVF, and smallest in lead II (indicative of right coronary artery occlusion).

Figure 3. The electrical activity on an ECG (EKG). The areas represented on the ECG are summarized below: V1, V2 = RV; V3, V4 = septum; V5, V6 = L side of the heart; Lead I = L side of the heart; Lead II = inferior territory; Lead III = inferior territory; aVF = inferior territory (remember ‘F’ for ‘feet’) aVL = L side of the heart; aVR = R side of the heart

There is left axis deviation . In addition, the PR interval is prolonged and constant suggesting first degree heart block . The 3 channel ECG uses 3 or 4 ECG electrodes. Red is on the right, yellow on the left arm, green on the left leg ('sun shines on the grass') and black on the right leg.

on Q waves in leads III and aVF in 31 patients ECG evidence of a pathologic Q wave is Table 1—Lead III Q Waves and Coronary Artery Disease*. Q-Wave

The measurement of a voltage requires two contacts and so, electrically, the unipolar leads are measured from the common lead (negative) and the unipolar lead (positive). A 12-lead ECG consists of three bipolar limb leads (I, II, and III), the unipolar limb leads (AVR, AVL, and AVF), and six unipolar chest leads, also called precordial or V leads, (,,,,, and). Limb leads: I, II, III, IV, V, and VI Lead IV also called AVR Lead V also called AVL It follows that the ECG waves in lead aVF, at any given instance, is the average of the ECG deflection in leads II and III. Hence, leads aVR/–aVR, aVL and aVF can be calculated by using leads I, II and IIII and therefore these leads (aVF, aVR/–aVR, aVL) do not offer any new information, but instead new angles to view the same information. aVF: positive T-wave, but occasionally flat. V1: Inverted or flat T-wave is rather common, particularly in women.
