Abstract

The recording system detects ECG signals and sonic phenomena in the range of about 20 to 120 Hz which can be heard simultaneously over a suitable isolation amplifier using a headset or seen using an oscillograph screen. The probe designed as a combined potential detector with capacitor microphone characteristics is used. The flexible probe with a dia. less than 2 mm, as well as accepting depolarisation signals(-ECG signals) in the heart along the two electrodes. Also is in the position to accept sound waves produced by the bloodstream, the heart valves and the heart muscle across capacitor microphone mechanism in the heart. These signals are converted in to electrical signals. ADVANTAGE - Using capacitor microphone as routine can derive sound phenomena from heart, to determine condition of blood, heart valves and heart muscle.

Description

Gattung des AnmeldungsgegenstandesGenus of Subject of registration

Die Erfindung betrifft die Möglichkeit im Herzen simultan elektrische Potentiale, die durch die Erregungsausbreitung erzeugt werden, und Schallwellen, die durch Blutstrom, Herzklappenbewegungen und Herzmuskelkontraktionen generiert werden, aufzunehmen und hörbar sowie sichtbar zu machen.The invention relates to the possibility electrical potentials simultaneously in the heart, generated by the spread of arousal and sound waves that pass through Blood flow, heart valve movements and Myocardial contractions are generated record and audible as well as visible do.

Stand der TechnikState of technology

Mittels Elektrokathetern ist es bereits gelungen, intrakardial elektrische Potentiale abzuleiten. Doch ist bislang noch kein Verfahren entwickelt worden, im Herzen direkt Schallphänomene abzuleiten, da die Mikrofontechnik noch keine ausreichend kleinen Geräte vorgestellt hat, die in der Lage wären, routinemäßig Schallphänomene aus dem Herzen abzuleiten. Darüber hinaus ist noch nie eine Registrierkopplung von Repolarisationspotentialen (EKG-Signal) und Herzmuskel - bzw. Herzklappenantwort (Phono-Signal) intrakardial geglückt.It is already using electrocatheters succeeded in intracardially electrical potentials to derive. However, no method has yet been developed in the heart directly sound phenomena derive because the microphone technology not yet presented sufficiently small devices that would be able to routinely Derive sound phenomena from the heart. In addition, there is never a registration link of repolarization potentials (ECG signal) and heart muscle or heart valve response (Phono signal) succeeded intracardially.

Lösungsolution

Gelöst wurde dies Problem durch die weniger als 2 mm durchmessende bipolare, flexible Sonde, die im unbewegten Blut als Kondensator betrachtet werden kann und im Falle der Blutströmung als Resultat auf Herzmuskelkontraktion oder Herzklappenbewegung mit nachfolgender Veränderung des Elektrodenabstandes alle Kriterien eines hochohmigen KONDENSATORMIKROFONS erfüllt. Durch geeignete Verschaltung der Kanäle kann ein Schwingkreis aufgebautt werden, der einen Bandpaßfilter erzeugt und nur relevante Frequenzen passieren läßt.This problem was solved by the less as 2 mm diameter, bipolar, flexible Probe in the still blood as a condenser can be considered and in the case of Blood flow as a result of heart muscle contraction or heart valve movement with subsequent change in the electrode spacing all criteria of a high impedance CAPACITOR MICROPHONES met. By connecting the channels appropriately a resonant circuit can be built up, the one Bandpass filter generated and only relevant Frequencies can pass.

Erstmals ist es möglich direkt im Herzen Schallphänomene abzuleiten und sogar unmittelbar als Antwort auf die Depolarisationspotentiale hörbar oder sichtbar zu machen.For the first time it is possible right in the heart Derive sound phenomena and even immediately in response to the depolarization potential to make it audible or visible.

Dadurch könnten neue und unter Umständen bahnbrechende Informationen und Zusammenhänge über die elektromechanische Kopplung im Herzen gewonnen werden.This could create new and possibly groundbreaking information and context via the electromechanical coupling be won in the heart.
