ECG features suggesting VT:
• AV dissociation
• qR pattern in lead aVR with q wave >40ms
• Taller left rabbit ear
this arrhythmia is an example of idiopathic fascicular Ventricular tachycardia which is characterized by features of VT and the followings:
• QRS duration 100 – 140 ms. this is narrower than other forms of VT
• Short RS interval (onset of R to nadir of S wave) of 60-80 ms. the RS interval is usually > 100 ms in other types of VT
• RBBB Pattern
• Axis deviation depending on anatomical site of re-entry circuit
• AV dissociation
• qR pattern in lead aVR with q wave >40ms
• Taller left rabbit ear

The ECG shows group beats in which the last beat is a PVC and the others are sinus beats (shown as “S”).
The first step in the ECG interpretation is determining the rhythm. so first look for p waves. the best leads for recognizing the p waves are lead II and V1. if you can’t see P waves in these leads, look at all the leads. in this strip P waves are visible in the lead V3. Note that some of P waves are hidden behind the prior T waves.

Inferior MI is characterized by presence of ST-elevation in inferior leads (II, III and aVF) and may result from occlusion RCA, LCX and less commonly LAD.
RCA occlusion (80%) is suggested by:
ST elevation in lead III > lead II
Presence of reciprocal ST depression in lead I
Signs of right ventricular infarction: STE in V1 and V4R
Circumflex occlusion (18%) is suggested by:
ST elevation in lead II >= lead III
Absence of reciprocal ST depression in lead I
Signs of lateral infarction: ST elevation in the lateral leads I and aVL or V5-6
LAD occlusion (2%) is suggested by:
simultaneous ST elevation in the precordial and inferior leads

ST elevation in lead III > lead II
