Contribution of the electroencephalogram in monitoring cardiac dysrhythmias

It is often difficult to distinguish between episodic cerebral symptoms resulting from primary disorders of the brain and those resulting from cardiac dysrhythmias. When patients with such symptoms are referred for electroencephalography, the electrocardiographic activity recorded concurrently can provide additional useful diagnostic information. Two cases are presented to illustrate the contribution of the electro-encephalogram in the diagnosis of significant cardiac dysrhythmias.
