And a resting heart rate higher than 85 is usually an indication that your thyroid medication/levothyroxine dose is too high
When my resting heart rate goes up like that and the heart beats stronger as well I know that I am hyperthyroid
Hypothyroidism affects between 4% and 10% of the population, and the prevalence of subclinical hypothyroidism is reported to be as high as 10% in various
Synthroid (levothyroxine) is a synthetic thyroid hormone that treats hypothyroidism and cancer
The effects of thyroid dysfunction on the cardiovascular system have been well documented for >2 centuries
This study showed that patients with hypothyroidism had an increased risk of developing heart problems as compared with patient with normal thyroid function whether they were

The major cardiovascular changes that occur in hypothyroidism include a decrease in cardiac output and cardiac contractility, a reduction in heart rate, and an
This can happen when thyroid hormone replacement drugs like
A slower heart rate can decrease tissue perfusion, fatigue, and low energy
Moreover, evidence suggests that although long-term levothyroxine therapy increases daily heart rate by approximately 10 percent, it does not significantly affect the frequency of arrhythmias such as premature ventricular and atrial contractions (PVCs and PACs)
Levothyroxine can cause heart-related side effects, such as an increased heart rate or heart palpitations
This medication is a synthetic form of thyroxine (T4) that mimics the thyroid hormone in the human body
A fast heart rate and fatigue are just two of the signs your thyroid medication dose is too high
It is the most commonly prescribed medication for hypothyroidism

Abstract
In the June issue of the Journal of Clinical Endocrinology & Metabolism (JCEM), a large study revealed that among participants with congestive heart failure, having hypothyroidism — even the mild form — significantly increases the risk of death compared to people with normal thyroid function
It is the main treatment for hypothyroidism or an underactive thyroid gland

When you started, or increased, your levothyroxine dose did it cause your heart rate to go up? I just increased from 25 mcg to 50 and I’ve been dizzy & had a high heart rate
Over-the-counter decongestants also cause issues with blood pressure and heart rate, which may then be worsened by interactions with levothyroxine
