Ejection fraction is at 21% according to Echo and MRI - #2712

Jay Miller

I went to the doctor because my Apple Watch said my heart rate was at 37-41 while working out. I thought my watch was functioning improperly so I checked it with my BP cuff. I had the same reading. After an ultrasound and an MRI, my EF is at 21%. My left side is enlarged, and I have LBBB. I’ve always monitored my HR and BP for the past few years. I’m very active, and workout 4-5 times a week. I’ve never been on meds before, but the doctor put me 4 different meds and wants me to get a defibrillator. This is all happening so fast and I don’t want to jump the gun. Can EF improve with meds only?

An ejection fraction (EF) of 21% is significantly lower than normal, as the typical EF ranges from 50-70%. It indicates that the heart is not pumping blood as efficiently as it should, which can lead to symptoms like low heart rate and fatigue. This can happen with conditions like left bundle branch block (LBBB) and heart failure, which can cause the left side of the heart to enlarge.

In some cases, medications can help improve heart function, but a low EF often requires additional treatments. The medications your doctor prescribed are likely aimed at improving heart function and preventing further damage. However, a defibrillator might be recommended to help prevent life-threatening arrhythmias due to the low EF and your LBBB.

While the goal of treatment is to improve heart function, it’s important to follow your doctor’s advice and attend regular follow-ups to monitor progress. With the right combination of medications and devices like a defibrillator, many patients experience stabilization or improvement in their condition.
