Normal sinus rhythm
Normal sinus rhythm is characterized by a regular rhythm originating from the sinus node between 60-100 beats per minute. Each impulse follows the normal conduction pathway with visible P waves preceding upright QRS complexes and normal PR and QT intervals. Normal sinus rhythm serves as the standard against which all other cardiac rhythms are compared.

The ECG shows regular sinus rhythm at a rate of 88 beats per minute with intermittent conduction block such that every third P-wave is not followed by a QRS complex, resulting in a ventricular rate of 59 beats per minute. Further analysis of the ECG found normal QRS axis, duration and morphology with no signs of infarction, hypertrophy, or other abnormalities. The final diagnosis was sinus rhythm with Mobitz type 1 2nd degree AV block and a ventricular rate of 58 beats per minute.
ECG #10 - ID122 - Atrial Flutter
This document describes the stepwise interpretation of ECG ID 122, which shows atrial flutter with variable atrioventricular block and a ventricular rate of 107 beats per minute in a 50-year-old man complaining of palpitations. The interpretation examines the P waves, QRS complex, QRS duration, signs of ventricular hypertrophy or myocardial infarction, and T waves. The final diagnosis is atrial flutter with variable AV block and a ventricular rate of 107 beats per minute.
ECG #9 - ID594a - acute ASMI
This ECG shows signs of an acute antero-septal myocardial infarction in a 49-year old man presenting with chest pain, requiring urgent therapy. The ECG reveals normal sinus rhythm, a normal QRS axis and duration, and marked ST elevation in leads V1-V4, consistent with an antero-septal injury pattern diagnostic of an acute antero-septal infarction.
ECG #2 - ID 352 - Premature Atrial Complexes
A 62-year-old man presented with palpitations. An analysis of his ECG found sinus rhythm at 83 bpm with premature atrial complexes, where every third P wave was premature in a pattern of trigeminy. The QRS complexes, ST segments, and T waves were normal with no signs of right or left atrial enlargement, bundle branch blocks, ventricular hypertrophy, or myocardial infarction. The final diagnosis was sinus rhythm with atrial premature complexes in a pattern of trigeminy, but an otherwise normal ECG.
ECG #1 - ID 380 – Normal ECG
The ECG is for a 53-year-old man undergoing pre-anesthesia evaluation. The interpreter found normal sinus rhythm at a rate of 60 bpm, normal P waves and PR interval, normal QRS axis and duration with no evidence of conduction blocks, no signs of chamber enlargement or hypertrophy, and normal ST segments and T waves. The final diagnosis was a normal ECG.
ECG #4 - ID 383 – Atrial fibrillation
A 76-year-old woman underwent an ECG examination in her family doctor's office which showed atrial fibrillation with an irregularly irregular ventricular rhythm of 66 beats per minute and no P waves. The QRS complexes were normal with no signs of conduction abnormalities, ventricular hypertrophy, or prior myocardial infarction. The final diagnosis was atrial fibrillation with a controlled ventricular rate of 66 bpm and no other abnormalities.
ID 352 –Sinus rhythm With premature atrial complex
A 62-year-old man presented with palpitations. An analysis of his ECG found sinus rhythm at 83 bpm with premature atrial complexes, where every third P wave was premature in a pattern of trigeminy. The ECG further showed normal P waves, QRS axis, duration and complexes, as well as normal ST segments and T waves. The final diagnosis was sinus rhythm with atrial premature complexes in a pattern of trigeminy, but an otherwise normal ECG.
Atrio-ventricular dissociation
Atrio-ventricular dissociation occurs when the atrial and ventricular rhythms are independent of each other. It can happen when the atrial rate slows below the intrinsic ventricular rate, or due to inappropriate acceleration of the ventricular rate. Typically in AV dissociation the distal pacemaker, such as the ventricles, beats faster than the proximal pacemaker like the atria. In complete heart block the proximal pacemaker usually beats faster than the distal one. However, there are exceptions to using pacemaker rates to distinguish the two.
Lead errors: reversal of limb leads
This document discusses common errors involving limb leads in electrocardiograms (ECGs), including:
1) Lead reversal is a common error, such as switching the right and left arm leads. This can cause leads like aVR and aVL to be reversed.
2) Misplacing the ground cable, such as attaching it to the right arm instead of the right leg, is another error.
3) Complex misplacements of the limb leads are less common. Examples provided demonstrate how specific lead errors can cause abnormalities to appear or disappear on ECG tracings.
Stepwise interpretation of ECG - #9 no Dx ID 594
This ECG shows a 49-year-old man experiencing severe chest pain for 1 hour who is presenting with an antero-septal injury pattern consistent with an acute myocardial infarction requiring urgent therapy. The ECG shows normal sinus rhythm at 84 beats per minute, a normal PR interval and QRS axis, and no signs of ventricular hypertrophy. It does reveal marked ST elevation in leads V1-V4, confirming the diagnosis of an acute antero-septal infarction.
Stepwise interpretation of ECG - #13 no Dx ID 419
This ECG shows an ectopic atrial rhythm originating outside the sinoatrial node at a rate of 75 beats per minute. The P waves precede each QRS complex but have an abnormal axis. There is also evidence of incomplete right bundle branch block seen by a widened QRS complex with a duration of 100 milliseconds and rSR' pattern. The final diagnosis is an ectopic atrial rhythm at 75 bpm with incomplete right bundle branch block and no signs of ventricular hypertrophy, myocardial infarction, or abnormal ST segments or T waves.

This ECG shows an ectopic atrial rhythm originating outside the sinoatrial node at a rate of 75 beats per minute. The P waves have an abnormal axis and precede each QRS complex, indicating the atrial origin. There is also an incomplete right bundle branch block seen by the prolonged QRS duration of 100 milliseconds and rSR' pattern. The final diagnosis is an ectopic atrial rhythm at a rate of 75 bpm with an incomplete right bundle branch block.
Stepwise interpretation of ECG - #13 no Dx ID 419
This ECG shows an ectopic atrial rhythm at a rate of 70 beats per minute with an incomplete right bundle branch block pattern. The QRS axis is normal and the duration is 100 msec. with an rSR' configuration. There are no signs of ventricular hypertrophy, myocardial infarction, or abnormal ST segments or T waves. The final diagnosis is an ectopic atrial rhythm at 75 beats per minute with an incomplete right bundle branch block.

Stepwise interpretation of ECG - #13 no Dx ID 419
Ectopic atrial rhythm at a rate of 75 beats per minute. P waves are clearly seen and negative in several leads, indicating they do not originate from the sinus node but likely a low atrial region. There is also an incomplete right bundle branch block present as shown by a prolonged QRS duration of 100 milliseconds with an rSR' pattern. The final diagnosis is an ectopic atrial rhythm at a rate of 75 beats per minute with an incomplete right bundle branch block.

Stepwise interpretation of ECG - #12 no Dx ID 111
A 56-year-old man presented with an episode of syncope. An ECG was performed which showed sinus rhythm with complete heart block, where the atrial rate was 80/min and the ventricular rate was 43/min. The dissociation of the P waves and QRS complexes along with the narrow QRS escape rhythm indicated the ventricular activation was coming from the AV junctional area. The ECG was otherwise normal.

A 67-year-old woman presented with palpitations. Her ECG showed a narrow-QRS tachycardia of 160 beats per minute. P waves were visible and preceded the QRS complexes, with a PR interval of 140 msec. The arrhythmia was diagnosed as atrial tachycardia based on the P wave morphology and timing.
