ecg description figure 1 demonstrates what appears to be sinus tachycardia with left bundle-branch block. closer evaluation of the rhythm strip reveals a p wave that is partially obscured by the t wave consistent with 2:1 atrioventricular (av) conduction suggestive of infranodal disease (red ...
Themiddle lettersof the names help you remember which bundle branch block each name is referring two (two Ls in WiLLiaM = left bundle branch block, two Rs in MaRRoW = right bundle branch block). Each name’sfirstandlast letterhelps you recognise the ECG features of the associated bundle bra...
• Right bundle branch block (RBBB)—The right bundle is blocked. Depolariza- tion spreads from the left bundle through the left ventricle away from lead V1, producing a negative deflection in V1. After a delay, the depolarization spreads from the left ventricle through the right towards V...
Gozensky and Thorne introduce the term 'Rabbit ears' to electrocardiography. Rabbit ears describe the appearence of the QRS complex in lead V1 with an rSR' pattern (good rabbit) being typical of Right Bundle Branch Block and an RSr' (bad rabbit) suggesting a ventricular origin i.e. ventric...
We train a DNN to detect: 1st degree AV block (1dAVb), right bundle branch block (RBBB), left bundle branch block (LBBB), sinus bradycardia (SB), atrial fibrillation (AF) and sinus tachycardia (ST). These six abnormalities are displayed in Fig.1. ...

Right bundle branch block Nodal (junctional) premature Ventricular escape Unclassifiable Atrial escape Supraventricular premature Nodal (junctional) escape Complying with the ANSI/AAMI EC57:1998 recommended practice [9], we excluded 4 records which are from patients with pacemakers, because records conta...
