I'm wondering if taking a beta blocker before getting an ECG might hide any signs of a heart attack. Could it affect the results or mask any important signals that might indicate a problem?
Taking a beta blocker before an ECG can indeed affect the results by potentially masking or hiding signals of a heart attack. Beta blockers can lower heart rate and blood pressure, which may impact the ECG readings. It is generally recommended to avoid taking beta blockers before an ECG if there is suspicion of a heart attack. If you are scheduled for an ECG and are taking beta blockers, it is advisable to consult with your healthcare provider about whether to temporarily stop the medication before the test.
