IMPRESSION: The finding of sinus bradycardia with 1st-degree AV block + marked sinus arrhythmia + the change in PR interval from beat #5-to-beat #6 — suggests a form of vagotonic block ( See My Comment in the October 9, 2020 post in Dr. Smith's ECG Blog ). Initial high sensitivity troponin I returned at 6ng/L (normal 0.20

Finally, do a coronary angiogram Possible alternative to pacing is to give a beta-1 agonist to increase heart rate. Use Lidocaine instead (lidocaine prevents the PVCs which cause R on T, and does not prolong the QT.) Discontinue all QT proloning medications, including azithromycin 6. Dobutamine is an acceptable alternative.

Patient was planned to gradually start cardiac rehab.Discussion:CCF is a rare anomalous connection between coronary arteries and a cardiac chamber or other major blood vessels of the heart. However some patients can develop heart failure, angina, and arrhythmia due to significant intracardiac shunt or coronary steal phenomenon.
