Your blood pressure of 130/60 mmHg is in a reasonable range, and your kidney marker (creatinine of 1.32 mg/dL) is only slightly elevated, which is quite common. However, your slow heart rate (bradycardia) requires professional attention. Switching from Eptus (eplerenone) to Lasix (furosemide) can change your fluid and potassium levels, which directly affects your heart rhythm. Please contact your doctor promptly. They will likely want to check your blood electrolytes and perform a quick electrocardiogram (ECG) to ensure your heart is beating safely.
