Absence of P Waves A lack of visible P waves preceding QRS complexes suggests a lack of sinus beats ; this may occur with sinus dysfunction or in the presence of fibrillation or flutter waves. The P wave may also be hidden within the QRS complex.
Read moreCan atrial fibrillation have P waves?
Diagnosis – Atrial Fibrillation. The diagnosis of atrial fibrillation is confirmed with a standard 12-lead ECG. P waves are absent , coarse “fibrillatory waves” can frequently be seen and sometimes no atrial activity can be identified. The QRS complexes are “irregularly irregular”, with varying R-R intervals.

Key Recommendations Lenient rate control (<110 beats per minute resting) is recommended over strict rate control (<80 beats per minute resting) for patients who have atrial fibrillation. The risk of stroke and bleeding should be discussed with all patients considering anticoagulation.
Read moreDoes atrial flutter have P waves?
This is because the P waves (flutter waves) in atrial flutter occur at about 250-350 per minute (usually around 300) . At this rate, it can appear that there is a P wave in front of each QRS and a T wave after each QRS.15 Kas 2016

“Based on our study, digoxin should be avoided in patients with AFib , particularly if symptoms can be alleviated with other treatments,” Lopes said. “We showed that starting digoxin was associated with increased risk of death and sudden death, regardless of the presence of heart failure.

The cardiac manifestations are the most concerning and can be fatal. Digoxin toxicity can induce literally every arrhythmia except for rapidly conducted atrial arrhythmias (atrial fibrillation and atrial flutter) .
