This means they will probably be given regular blood tests to see if their digoxin level is correct. Levels that are too high can cause loss of appetite, nausea or vomiting, and headaches. Digoxin can also occasionally interfere with the normal heartbeat, causing irregular heartbeats or skipped beats. These side effects should be reported to the doctor immediately. The heart tries to compensate for its weakened pumping action by beating faster, which puts more strain on it.
Beta blockers reduce the heart's tendency to beat faster.
This allows the heart to maintain a slower rate and lowers blood pressure. Beta blockers are used for mild to moderate heart failure and often with other drugs such as diuretics , ACE inhibitors and digoxin . Since beta blockers reduce the heart rate, they also decrease the amount of oxygen that circulates through the body. This means that people taking them might become less able to handle strenuous physical activity. They might feel nauseated and weak after lifting or working hard.
