Describe the parts of the ECG. Ectopic atrial tachycardia or simply atrial tachycardia occur when an ectopic focus in one of the atria discharges impulses at a higher rate than the sinoatrial nodeThis is due to abnormal automaticity or re-entry triggered activity is much less common taking place in the ectopic focus. This ECG shows inverted P waves in inferior leads II III and aVF.
ECG Axis Interpretation From Life In The Fast Lane Posted on May 31 2019 by Tom Wade MD I will be erasing the post below and changing it to the title blog post.
