          Abstract

          Interatrial block (IAB; P wave ≧110 ms) indicates conduction delay between the right and left atria. IAB can present as partial or advanced and is denoted on the electrocardiogram (ECG) by bifid or biphasic P waves, respectively, the latter in inferior leads. The importance of IAB cannot be overemphasized due to high prevalence, especially at ages 60 and over, and due to grave associations with atrial flutter and fibrillation as well as congestive heart failure. Thus, we present a classic ECG of the much less common form of IAB, namely advanced IAB, as it serves as an excellent yardstick and teaching tool to help clinicians understand this medical entity thoroughly and to easily recognize this often missed type of block.

          Electromechanical dysfunction of the left atrium associated with interatrial block.

          S. Goyal, David Spodick (2001)
          Our purpose was to determine the effect of interatrial block (IAB, P-wave duration >/=120 ms) on left atrial (LA) dynamics. IAB is associated with LA enlargement (LAE). LA dysfunction is associated with decreased left ventricular filling, a propensity for LA appendage thrombus formation, and reduced atrial natriuretic peptide levels. We evaluated LA function in patients with and without IAB matched for LA size. Echocardiograms with LA enlargement were analyzed. Twenty-four patients had IAB, and 16 patients without IAB formed the control group. LA volumes, A-wave acceleration times (At), LA stroke volume (LASV), ejection fraction (LAEF), and kinetic energy (LAKE) were calculated. The control group and patients with IAB had comparable maximal LA volume and diameter (P >.05). Patients with IAB had significantly longer At (115 +/- 39 ms vs 83 +/- 24 ms, P <.01) and smaller LASV (7 +/- 5 mL vs 17 +/- 6 mL, P <.01), LAEF (9% +/- 6% vs 25% +/- 8%, P <.01), and LAKE (20 +/- 14 vs 65 +/- 44 Kdyne/cm/s, P <.01). LAKE varied inversely with P-wave duration (r = -0.51, P <.01). P-wave duration and minimal LA volume were independent determinants of LAEF. Patients with IAB have a sluggish, poorly contractile LA, and the extent of dysfunction is related to the degree of electrical delay from IAB. IAB should be considered a marker of an electromechanically dysfunctional LA and hence a risk factor for atrial fibrillation and congestive heart failure.
