A segment of a town or city surrounded by streets and avenues on at least three sides and usually occupied by buildings, though it may be composed solely of vacant lots. The section of a city enclosed by streets that is described by a map which indicates how a portion of land will be subdivided.

Another clinical consideration in this case is the timing of permanent pacemaker placement in a patient with complete heart block due to metastatic disease.
One should be aware of the diagnostic signs of cardiac tamponade and complete heart block in the setting of metastatic disease and be able treat the patient appropriately.
Complete heart block with perforated interventricular septum following contusion of the chest.
The heart failure was probably a combination of 40 years of complete heart block, causing considerable dilatation of both ventricular cavities with superimposed systemic hypertension for many years.
In summary, we describe a patient who underwent cardiac transplantation because of heart failure and was found to have a large scar in his ventricular septum and fibrosis of his atrioventricular nodal area, suggesting that he had complete heart block for 40 years.
3) who underwent DOD pacemaker implantation following admission for complete heart block.
Conclusions: In elderly patients with complete heart block and unimpaired systolic function undergoing DOD pacemaker implantation, both ventricles share a similar pattern of diastolic function adaptation to AVI modifications and that might be the reflection of ventricular interaction under this specific pacing mode.
Anyway, patients with complete heart block are usually old and ventricular interdependence might not exist.
We have recently published a paper assessing LV diastolic function and atrial natriuretic peptide levels adaptation to variable AVIs in patients with complete heart block and normal LV and RV systolic function undergoing DDD pacing (9).
The present study demonstrates that DDD pacing mode in patients with complete heart block and a relatively preserved LV and RV systolic functions, is associated with a similar pattern of diastolic function adaptation of both ventricles to various AVI modifications and that might be the reflection of ventricular interaction during this pacing mode.
This statement of course stands for patients with complete heart block, normal or near normal LV systolic function with no evidence of coronary artery disease or conditions affecting RV performance.
The results of the present study suggest that in elderly patients with complete heart block and normal RV and LV systolic function, RV adapts to DOD pacing mode and AVI modifications in an analogous and sustained manner to the LV and this finding exhibits a mode of ventricular interaction.
