Preface
How to face 'the faces' of cardiac pacing represents an editor's compiled
selection of lectures on cardiac pacing and electrophysiology.
Electrical stimulation of the heart is an ever-changing and, at times,
explosive field. The number of implanting centres is growing tremendously
and pacing is not exclusively confined to arrhythmologists. Therefore, the
editors attempted to organize a course being both practical in daily clinical
management and instructive in understanding technical concepts.
The glossary of terms have to be clearly understood before one is able to
interpret the complex electrocardiograms of DDD and especially DDDR
pacemakers. Those electrocardiograms have to be approached in a system
atic way, using a step-by-step analysis.
The main clinical symptom requiring pacemaker implantation is syncope.
It cannot be over-emphasized that syncope is a clinical diagnosis merely
based on history and physical examination.
The organization of a pacemaker follow-up clinic depends on local
facilities and needs. The effectiveness of pacing controls markedly increases
when using a systematic approach. Repeated optimal adjustment of pro
grammable functions is part of the control.
Antiarrhythmic drugs are loosing popularity in the treatment of tachy
arrhythmias. Nonpharmacologic treatment (antitachypacing, implantable defi
brillators and antiarrhythmic surgery) at the present time have definite
indications, probably expanding in the future.
When complexity in electronic devices increases, repercussions on ex
penses, either by the government or social and private insurances, needs
consideration.
We are grateful to the contributors of this volume. By editing this text, we
have learned a great deal, and we hope you will enjoy facing the 'faces' of
pacing.

INTRODUCTION
Definition. Syncope is defined as a transient loss of consciousness with
spontaneous recovery. Syncope should not be confused with dizziness,
unsteadiness, coma or shock. Epileptiform seizures usually are absent.
However, they do occur when the attack is prolonged. Loss of consciousness
in the presence of focal neurologic signs should be defined as a transient
ischemic attack (TIA).
Incidence. Syncope is a common medical problem occurring in approxi
mately 20% of the population [1, 21. Although it can be assumed that most
people with a syncopal episode don't seek medical attention, nevertheless,
syncope accounts for 3% of the emergency room admissions and 1% of the
total hospital admissions in the USA. When recurrent, it may account for
more than 10% of the total population undergoing invasive electrophysio
logical investigations.
CAUSES OF SYNCOPE
Syncope has many causes, ranging from benign disorders (e.g. vasodepressor
or hyperventilation syncope) which are usually clinically unimportant, to
serious conditions (e.g. complete heart block, ventricular tachycardia) which,
if unrecognized, may result in fatality. Today's syncope may represent
tomorrow's sudden death.
Syncopal attacks are transient, so patients are usually seen when recovered
and the cause often is not apparent. There is a high spontaneous resolution
rate in up to two thirds of untreated patients with syncope. In the same
patient, the repetitions of syncope may have more than one cause. One
should be aware that simply finding an obvious cause (e.g. postural hypo
tension secondary to overmedication) should not stop the search for other
