Unmasking of atrial repolarization waves using a simple modified limb lead system.

CONCLUSION: The end of the Ta wave is not observable in sinus rhythm subjects, as it extends into the QRS complex and ST segment. In AV block patients, the Ta wave duration was generally '3' to 'three' times longer than the observable Ta duration in sinus rhythm subjects. PMID: 25550180 [PubMed - as supplied by publisher]
