The apparatus may include a housing with a small or reduced form factor near the size of a credit or debit card, so as to allow a user to obtain e.g., an electrocardiogram (ECG) measurement from various locations. The apparatus may include an electrode assembly comprising a set of electrodes disposed on the housing to perform an ECG by sensing an electrical signal corresponding to heart activity of a user when in contact with skin of the user and output the electrical signal. The apparatus may detect or generate six or more ECG leads. ## Claims ### Claim 1 An apparatus comprising: a housing having a credit card form factor; a set of electrodes to generate signals corresponding to electrical activity of a heart of a user; a memory; and a processing device operatively coupled to the memory, the processing device to: perform a multi-lead electrocardiogram (ECG) using the set of electrodes; and transmit data corresponding to the multi-lead ECG to a computing device. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein to perform the multi-lead ECG, the processing device is to: in response to the user making contact with each of the set of electrodes, measure a signal generated by each of the set of electrodes to record three ECG leads; and synthesize, using an algorithm, one or more additional ECG leads using the recorded three ECG leads, wherein the data corresponding to the multi-lead ECG comprises the recorded three ECG leads and the one or more additional ECG leads. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the housing has a multi-layered structure comprising: a lower layer having the set of electrodes, the memory, and the processing device mounted thereon; and an upper layer to expose one or more of the set of electrodes. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein a first electrode of the set of electrodes is mounted on an underside of the lower layer. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the first electrode protrudes beyond an edge of the underside of the lower layer. ### Claim 6 (depends on 3) The apparatus of claim 3, wherein a first electrode and a second electrode of the set of electrodes is mounted on a topside of the lower layer and are exposed by the upper layer. ### Claim 7 (depends on 1) The apparatus of claim 1, further comprising: a bar code, to provide access to the data corresponding to the multi-lead ECG in response to being scanned by any appropriate device. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the housing comprises: a first layer; a second layer; and an inlay sandwiched between the first and second layers, wherein the set of electrodes, the memory, and the processing device are integrated with the inlay. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the housing comprises a polymer material. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the housing comprises a plastic material. ### Claim 11 A system comprising: a monitoring device comprising: a housing having a credit card form factor; a set of electrodes to generate signals corresponding to electrical activity of a heart of a user; a memory; and a processing device operatively coupled to the memory, the processing device to: perform a multi-lead electrocardiogram (ECG) using the set of electrodes; and transmit data corresponding to the multi-lead ECG; and a computing device to: receive the data corresponding to the multi-lead ECG; process the data corresponding to each lead of the multi-lead ECG to generate a set of additional ECG leads; and display each lead of the multi-lead ECG and the set of additional ECG leads. ### Claim 12 (depends on 11) The system of claim 11, wherein to perform the multi-lead ECG, the processing device is to: in response to the user making contact with each of the set of electrodes, measure a signal generated by each of the set of electrodes to record three ECG leads; and synthesize, using an algorithm, one or more additional ECG leads using the recorded three ECG leads, wherein the data corresponding to the multi-lead ECG comprises the recorded three ECG leads and the one or more additional ECG leads. ### Claim 13 (depends on 11) The system of claim 11, wherein the housing has a multi-layered structure comprising: a lower layer having the set of electrodes, the memory, and the processing device mounted thereon; and an upper layer to expose one or more of the set of electrodes. ### Claim 14 (depends on 13) The system of claim 13, wherein a first electrode of the set of electrodes is mounted on an underside of the lower layer. ### Claim 15 (depends on 14) The system of claim 14, wherein the first electrode protrudes beyond an edge of the underside of the lower layer. ### Claim 16 (depends on 13) The system of claim 13, wherein a first electrode and a second electrode of the set of electrodes is mounted on a topside of the lower layer and are exposed by the upper layer. ### Claim 17 (depends on 11) The system of claim 11, further comprising: a bar code, to provide access to the data corresponding to the multi-lead ECG in response to being scanned by any appropriate device. ### Claim 18 (depends on 11) The system of claim 11, wherein the housing comprises: a first layer; a second layer; and an inlay sandwiched between the first and second layers, wherein the set of electrodes, the memory, and the processing device are integrated with the inlay. ### Claim 19 (depends on 11) The system of claim 11, wherein the housing comprises a polymer material. ### Claim 20 (depends on 11) The system of claim 11, wherein the housing comprises a plastic material.
