Overview
There are no ECG findings associated with Bipolar disorder. The use of lithium is associated with both atrial and ventricular electrical instability, even when lithium levels are in the therapeutic range. ECG is important before starting lithium or tricyclic antidepressant therapy.
Electrocardiogram
- There are no ECG findings associated with Bipolar disorder.
- Reduced vagal tone and higher levels of inflammatory biomarkers may distinguish Bipolar disorder from major depression and reveal an underlying pathophysiology of depression involving ANS dysfunction and chronic immune system dys-regulation.[1]
- In the study, patients with bipolar disorder had higher blood levels of inflammation biomarkers than patients with major depression.[2]
- The use of lithium is associated with both atrial and ventricular electrical instability, even when lithium levels are in the therapeutic range. TCA and some of the anti-psychotics, can affect the heart and cause conduction problems. In older patients with bipolar disorder, on lithium or tricyclic antidepressant therapy, ECG is important before starting these medications .[3]
