n8n-nodes-cardiacsense

This is an n8n community node. It lets you use Cardiacsense FHIR API in your n8n workflows.

Cardiacsense is a comprehensive cardiac and health monitoring platform that provides real-time access to vital signs, heart rate data, cardiac conditions detection, and advanced cardiovascular metrics through FHIR-compliant APIs.

n8n is a fair-code licensed workflow automation platform.

Credentials

To use the Cardiacsense node, you need to configure the following credentials:

Prerequisites

• An active Cardiacsense integrator account
• API access token from Cardiacsense

Authentication Setup

1. Obtain your API token from your Cardiacsense integrator dashboard
2. In n8n, create new Cardiacsense API credentials
3. Enter your API token in the "API Token" field
4. Configure the base URL:
   • Base URL: Your Cardiacsense FHIR API endpoint (default: https://fhir.cardiacsense-cloud.com)

The node uses Bearer token authentication for all API requests.

Compatibility

• Minimum n8n version: 0.198.0
• Tested with: n8n v1.0.0+
• Node API version: 1

This node follows FHIR standards and uses LOINC/SNOMED-CT medical coding systems for data type identification.

Usage

Basic Workflow Example

1. Add the Cardiacsense node to your workflow
2. Select a resource (e.g., "Vital Signs")
3. Choose an operation (e.g., "Get Heart Rate")
4. Configure parameters:
   • Patient Email: [email protected]
   • Start Time: 2024-01-01
   • End Time: 2024-01-02
5. Optional settings:
   • Averaging Interval: Set time averaging in minutes
   • Ignore Metadata: Toggle for simplified response format

Data Format

The node returns data in two formats:

FHIR-compliant format (default):

[
	{
		"valueQuantity": {
			"value": "72.0"
		}
		// ... additional FHIR metadata
	}
]

Simplified format (when "Ignore Metadata" is enabled):

{
	"data": [
		{
			"value": "72.0"
		}
	]
}

Time Range Specifications

• Dates can be in YYYY-MM-DD format
• Date-time can be in YYYY-MM-DD HH:MM:SS format
• All times are processed according to the patient's configured timezone
