1. A method of automatically assessing a patient's risk of an acute cardiac event, the method comprising:
receiving, from the patient, risk assessment information comprising risk factors, wherein the risk assessment information is received by a processor;
storing a pre-existing risk score based on the risk assessment information;
receiving, from the patient, a sample electrocardiogram (ECG), wherein the patient self-records the sample ECG using a handheld apparatus, and receiving, from the patient, a current symptoms indication, wherein the current symptoms indication includes a plurality of self-reported patient symptoms;
determining, in the processor, an ECG risk score from the sample ECG and a baseline ECG, and a chest pain risk score indicating a level of cardiac risk based on the current symptoms indication, and using the ECG risk score, the pre-existing risk score, and the chest pain risk score to determine a post-test risk score, wherein the ECG risk score is classified into at least one intermediate category based on a comparison of a voltage difference between the sample ECG and the baseline ECG to a first threshold voltage and a second threshold voltage, wherein the first threshold voltage is less than the second threshold voltage; and
presenting, to the patient, a diagnostic report and patient action instruction based on the post-test risk score.
