Increased vagal tone: Depression of sinus node and AV node
See how digoxin PMID: 32043160 PMCID: PMC7900815 DOI: 10
As AF is a precursor to many other cardiac conditions, an annual ECG is helpful, but
Conclusion
Specific myocardial effects of cardiotoxic drugs have well-described electrocardiographic manifestations
This case illustrates the importance of clinician awareness of rare electrocardiogram (EKG) patterns of digoxin toxicity and visual resolution of fatal
A provider can give you digoxin immune fab to reverse digoxin’s effects if you have an overdose of digoxin
There has been no syncope, no injuries and the patient had no other clinical symptoms or signs, just the leg weakness

The normal physiology as we may know is 3 Na+ go out to in exchange for 2K+ returned to the cell
Frequent ECG measurement is therefore recommended to monitor both cardiac disturbances due to digoxin toxicity and potential worsening of pre-existing cardiac disorders
Hyperkalemia is defined as a serum or plasma potassium level above the upper limits of normal, usually greater than 5
Background: Studies of healthy volunteers or patients in sinus rhythm have indicated that treatment with digoxin produces characteristic changes in the electrocardiogram (ECG)
5 micrograms/mL
In rare cases, increased levels of digoxin in your blood can cause heart rhythm disturbances (arrhythmias)
K depleting drugs (increases likelihood of digitalis toxicity) Ca channel blockers
shortened QT interval characteristic down-sloping ST depression, reverse tick appearence, (shown here in leads V5 and V6) dysrhythmias ventricular / atrial premature beats paroxysmal atrial tachycardia with variable AV block Most studies examine ECG changes in TCA intoxication and are small or retrospective
1,2 ECG Patterns to Remember for Digoxin Toxicity Early Recognition of Digoxin Toxicity May Result in Improved Treatment OutcomesEarly Recognition of Life-threatening Digoxin Toxicity is Essential and may Result in Improved Treatment Outcomes1,2 INDICATION DIGIFab is indicated for the treatment of known (or strongly suspected) life-threatening
It is the only oral inotrope that does not increase long-term mortality in chronic heart failure and has few side effects when dosed appropriately on the basis of serum concentration
Exercise test and variance ECG were performed before and after pretreatment with digoxin orally
