Recurring palpitations deserve prompt medical assessment—don’t wait until you have spare time for routine bloodwork. If they are happening now and aren’t settling, or occur with chest pain, shortness of breath, faintness or fainting, seek emergency care. Noticing them only at night does not establish that they are harmless. nhs.uk
The timing after Anavar matters, but it doesn’t prove that Anavar caused the symptoms. Testosterone, other products or stimulants, and recent medication changes all need review. Antidepressant withdrawal can cause palpitations and sleep disturbance, but that possibility should not be used to dismiss a heart rhythm problem. sps.nhs.uk
Avoid taking more Anavar, stimulant pre-workouts or energy drinks, and pause intense training until assessed. Bring the product packaging and a complete list of doses, supplements and medication changes. A clinician may check your blood pressure, perform an ECG and order relevant blood tests; intermittent symptoms may require a wearable rhythm monitor. Routine bloodwork alone cannot rule out an arrhythmia.
PCT is not a treatment for palpitations. Get clinician guidance on stopping the non-prescribed cycle and managing hormone recovery rather than starting PCT, adjusting Arimidex or committing to a “cruise” yourself. The breast lump also needs examination. Contact your antidepressant prescriber before making further changes.
Finally, one low testosterone panel does not establish a lifelong need for TRT. Diagnosis usually requires symptoms, repeat morning testing and investigation of the cause. Current testosterone use complicates that assessment, and fertility should be discussed before ongoing treatment. www.endocrine.org
