This database consists of endocardial recordings from the right atria of 8
patients in atrial fibrillation or flutter. A decapolar catheter with 2-5-2mm
spacing (7mm spacing between bipoles) was placed in four separate regions of
the heart. In each region, the 5 bipolar signals were recorded along with 3
surface ECG leads. Data were digitized at 1kHz. Catheter bipoles are labeled
(distal to proximal) CS12, CS34, ..., CS90. Regions are:
- SVC
- The distal tip of the catheter (CS12) is close to the annulus of the
superior vena cava
- IVC
- The proximal tip of the catheter (CS90) is close to the annulus of the
inferior vena cava
- TVA
- The distal tip (CS12) is close to the tricuspid valve annulus
- AFW
- The entire catheter rests against the atrial free wall
The figure at left shows approximate catheter placement in a model heart (click
on any panel at left, or on the links below, for a larger view):
- A)
- Anterior view of a heart model,
with the interior of the right atrium (RA) and right ventricle (RV) exposed.
- B)
- Catheter placement for SVC,
where the distal tip is just inferior to the annulus of the superior vena cava,
and the catheter is against the posterior wall of the atrium. Eight poles
(black marks) of the decapolar catheter model (copper wire) are visible.
- C)
- Placement for TVA,
where the distal tip is on the tricuspid valve annulus and the electrodes are
against the septal wall.
- D)
- Placement for IVC,
with the proximal catheter end just superior to the annulus of the inferior
vena cava, and the electrodes against the posterior wall.
- E)
- Placement for AFW,
with the catheter against the atrial free wall (which is hinged open here).
The database includes a set of four records (one for each placement) for
each of the eight patients. The name of each record identifies the patient
(iaf1, iaf2, ..., iaf8) and the placement of the catheter (svc, ivc, tva, afw).
Each record contains eight signals (intracardiac: CS12 - CS90, or ECG: I, II,
V1, aVF). Each signal is sampled at 1 kHz with 14-bit resolution; the
signal amplitudes are uncalibrated.
The atrial free wall (afw) records are considerably longer than those for the
other regions, and include the effects of drug delivery and washout. During
these records, patients iaf1, iaf2, iaf6, and iaf8 received adenosine, and
patients iaf3, iaf4, iaf5, and iaf7 received Isuprel; the drug, dosage, and
delivery time(s) are noted in the .hea files of the afw records. Note
that these times are approximate, based on clinical notes taken during the
procedure.
The .qrs annotation files were produced using sqrs, and have not been corrected; they may be useful for
beginning a study of these recordings.
